[R] estimating mode
Dear all, I am considering a problem related to density regression. After we got the estimation of probability density function f(x), how can we estimate the mode of that population? Does the sm package support mode estimation? If not, is there any other function in R can estimate the mode according to the estimation of pdf f(x)? Univariate case is ok. If the function further support higher dimensions, it is perfect. Thanks. _ Take a break!

[R] GLMM (lme4) vs. glmmPQL output (summary with lme4 revised)
This is a summary and extension of the thread
GLMM (lme4) vs. glmmPQL output
http://maths.newcastle.edu.au/~rking/R/help/04/01/0180.html
In the new revision (#Version: 0.4-7) of lme4 the standard
errors are close to those of the 4 other methods. Thanks to Douglas Bates,
Saikat DebRoy for the revision, and to Göran Broström who run a
simulation.

Re: [R] Object validation and formal classes
On 29 Jan 2004 at 20:04, Robert Gentleman wrote: There are some efficiency issues that prevent constant checking (at least at the present time). There are also some other issues that need to be adequately addressed too. For example, suppose I had an object with two slots a - a character string b - the number of characters Yes, efficiency was also a concern I had with my original understanding of what the validation function is supposed to do. Reading the docs I got the impression that 1) during an assignment the validation function will be called with a copy of the object that already has the new value assigned 2) if it returns TRUE that copy is returned as the result of the assigment 3) otherwise, an error is raised. That would be pretty inefficient for large objects. What does actually happen when I call slot- ? I suppose that this always operates on the object in sys.parent() of slot- and never creates a copy of the specified object. and I set my validity checker to make sure that the length of the string is the number in b. Now that basically means that I can never change the string (except to other strings of the same length) if validity checking happened after every change. I somehow need changing both a and b to be instantaneous (which they currently are not). We have not really gone far enough down that path yet to know what the right thing is, but we are working on it. So for now validity checking occurs at a few specific points and if/when you ask for it. What about access control ? The docs state it isn't implemented yet. If there was something similar to C++ one could set critical slots to private and only allow access and assignment via (replacement) methods. At first sight, this seems feasible and shouldn't cost much performance. Another approach might be an (optional) validation function for each individual slot or for groups of slots that doesn't need to validate the whole object but only changes that may occur in conjunction with a single slot or group of slots. Of course, efficiency issues are more likely to occur in this scenario. The @- operator seems to call slot- by default, maybe I can overload slot- for my class and implement this kind of validation on my own ? I guess some tricks will be necessary here to prevent that slot- is called recursively if the validation function for one slot attempts to make an assignemt to another slot. So if I don't find a feasible solution in the meantime, the best way would be writing wrappers for those slots that need validation and tell the users to use those instead of changing the object directly ?

Re: [R] memory problem for R
Hello, Yun-Fan: Prof. Ripley's comments will get you started. Part of the key is finding informative ways to subset and summarize the data so you don't try to read it all into R at once. You can read segments using arguments skip and nrows in read.table. You can then analyze a portion, save a summary, discard the bulk of the data and read another portion. Beyond this, you may know that Kalman filtering is essentially linear regression performed one observation or one group of observations at a time, downweighting older observations gracefully. It essentially assumes that the regression parameters follow a random walk between observations or groups of observations. I've done ordinary least squares with Kalman filtering software one observation at a time, just by setting the migration variance to zero. R software for Kalman filtering was discussed recently in this list; to find it, I would use the search facilities described in the posting guide at the end of every r-help email. hope this helps. spencer graves Prof Brian Ripley wrote: On Thu, 29 Jan 2004, Yun-Fang Juan wrote: Here is the exact error I got -- Read 73 items Error: cannot allocate vector of size 1953 Kb Execution halted --- I am running R on Freebsd 4.3 with double CPU and 2 GB memory Is that sufficient?

Dear all,
I am considering a problem related to density regression.
After we got the
estimation of probability density function f(x), how can we
estimate the
mode of that population?
Does the sm package support mode estimation? If not, is there
any other
function in R can estimate the mode according to the
estimation of pdf f(x)?
Univariate case is ok. If the function further support higher
dimensions, it
is perfect.
Thanks.

Re: [R] Doubt about pattern
Your question has by now been answered but I thought
I would add that if you want to do it via file globbing on Windows
rather than regular expressions then this function would help:
list.files.glob - function( spec ) {
# returns list of files or NULL if none: spec uses globbing and can
# use either forward or backward slashes.
# e.g list.files.glob( c:/a*.* )
# e.g. list.files.glob( c:/myfolder/my*.dat)
# only works on Windows
if ( substring(spec,2,2) != : ) spec - paste( C, spec, sep= : )
z - system( paste(cmd /c attrib, spec), intern = T, invisible = T)
if ( !pmatch(File not found - , z[1], nomatch = 0) ) substring(z,12)
}
For example:
list.files.glob( *.sens )

to send for an object only the files that finish in .sens.. I execute the command
below,
files - dir(pattern=*.sens)
but it includes all of the files that have sens, independent of they be in the end
or in the middle of the name of the file. How could I solve this? I sought in the
html_help but I didn't find similar to this.
My files
script_sens.txt, Sen_155_01_R1.sens, Sen_155_01_R2.sens, Sen_155_01_R3.sens,
Sen_155_02_R1.sens, Sen_155_02_R2.sens, Sen_155_02_R3.sens,
Sen_155_03_R1.sens, Sen_155_03_R2.sens, Sen_155_03_R3.sens,
tome2sens_time1sens.txt
Tahnks very much

Re: [R] How to generate a report with graphics and tables?
Just to expand on an earlier suggestion:
I have some data sets which change on a daily bases. So far I have
imported these sets into R, done all my evaluations resulting in a
couple of plots, charts and tables of numbers which I copypasted via
clipboard into Powerpoint.
The procedure is always the same and I wonder, whether there is no
easier way for doing so. Is there some type of report generator
available or some HowTo on this.
Can anybody give me a hint on where to look for?
Regards,
Olaf Bürger
...
One other possibility is to use the R2HTML package (and maybe the xtable
package, too) to write the `report' in HTML.
HTH,
Andy
R2HTML is not (yet) as far along as Sweave, but depending on how much
sympathy you have for your clients, html can be a very nice solution. An
important requirement for many reports is that computer-naive clients be
able to edit and copy from the reports to an MS application, preferably
without severe font and formatting problems and without needing to
install/understand foo2bar type applications. See comments to this
effect in the recent R2HTML article by the package author, Eric Lecoutre in
the most recent R News (vol 3/3). As Andy noted, xtable is nice to use in
conjunction with R2HTML (just write a little xtable method like the one
following this message):
In particular, a naive user viewing the html file with Internet Explorer (I
know v. 5.5 or greater will work) will have an option, under the File menu
to Edit with Microsoft Word for Windows. This assumes they have set MS
Word as their HTML editor within IE. It also assumes some minimal formatting
requirements for the HTML file (but you can worry about this, the client
won't have to).
I find this solution keeps everyone happy:
1. I can auto-generate text source for my documents;
2. clients without proprietary software can view the report;
3. clients with standard MS software but without a clue can easily edit and
copy.
Cheers,
Jim

RE: [R] How to create own distance measure in cluster ?
The simplest way, if you have a function that returns the distance matrix,
is to use as.dist(). E.g.,
myDist - function(...) {
## compute distance matrix dmat.
...
return(as.dist(dmat))
}
I believe most clustering algorithms in R will accept dist objects.
If that doesn't do it, you can download the source for the `cluster' package
from CRAN.
Andy
From: Ricardo Zorzetto Nicoliello Vencio
Hi everyone,
I want to create my own distance measure, other than 'euclidean' or
'manhatan', to use in cluster pckgs. To do this I think that I need to
change dist(), in mva pckg, or daisy(), in cluster pckg. (or
is there a
cleaver way ?)
But this functions are in fact things like: .Fortran(
daisy, ... ) or
.C(dist,...).
I tried unsuccessfully to find source code of .Fortran or .C
function to
lear how R calculate dissimilarity matrix and then modify
source to add my
own distance metrix.
Could someone help me ? Help me to find .Fortran(...) source
or helpe me
with better idea to implement my own distance metrix ?

Jim,
I would really like to reiterate Professor Ripley's and Arne Henningsen
comments. The problem goes for any analytic software or system you might
want to use, not just R. My impression is that at least for part of it, you
want the individual users to use R as they would on their own desktops. (If
that is not the case, much of the rest of this note is pure FYI.) Even in
its most advanced 2003 Server edition, Windows is simply not designed to be
a multi-user system. Sure, it can reliably host a web server that may need
to run quick bursts of R batch-type jobs (analytics) and return results to
a client (e.g. web browser), but that does not sound like what you are
looking for (at least in part). And beyond the technical limitations, use of
Windows Terminal Server (Remote Desktop) / Citrix, etc. will cost much money
and implementation hassle and probably even legal headaches. We have had
colleagues here at Merck (over my and Andy Liaw's disbelief) that have tried
to shoehorn Windows this way, and even the speed of single, small jobs by 1
logged-on took longer on the server than on their much less powerful
laptops.
A Linux solution is very flexible, in our experiences (we have Windows XP as
corporate desktop standard). As stated, with Samba, you can map directories
that look like just another drive in Windows Explorer. Printing is just as
transparent in either direction. VNC (Virtual Network Computing) is very,
very nice to provide the individual user's Linux environment as just another
window on their Windows desktop. With the free utility of autocutsel,
clipboards can be synchronized for ease of cutting and pasting. And KDE, one
of several window manager analogues to Windows, is very sophisticated and
shares a lot in common with the Windows GUI from a user operations
standpoint. While it may sound like a hassle to get up and running now if
your shop is currently 99% Windows, the benefit will absolutely be clear
later.
Hope that helps,

(It is hard to imagine that the cases are from a single homogeneous population and that a linear model fits so well that the random error is not dominated by systematic error.) I tried 10% sample and it turned out the matrix became singular after I did that. Ther reason is some of the attributes only have zero values most of the time. The data i am using is web log data and after some transformation, they are all numeric.

Re: [R] Object validation and formal classes
It was never the intention that validity checking happen automatically on _every_ assignment of an object from the class--since those assignments take place frequently during evaluation of functions, the overhead would be unacceptable. And as Robert points out, one needs to postpone validity checking until a set of mutually dependent changes is finished. The Programming with Data description says that validity checking takes place on permanent assignment. But this was not written with R in mind, and the idea of permanent assignment is ambiguous in R. It could mean all assignments into the Global environment, or it could mean on serializing (saving the workspace, e.g.). If we agree on a useful interpretation, automatic validity checking might be reasonable in that sense in the future. Torsten Steuernagel wrote: On 29 Jan 2004 at 20:04, Robert Gentleman wrote: There are some efficiency issues that prevent constant checking (at least at the present time). There are also some other issues that need to be adequately addressed too. For example, suppose I had an object with two slots a - a character string b - the number of characters Yes, efficiency was also a concern I had with my original understanding of what the validation function is supposed to do. Reading the docs I got the impression that 1) during an assignment the validation function will be called with a copy of the object that already has the new value assigned 2) if it returns TRUE that copy is returned as the result of the assigment 3) otherwise, an error is raised. That would be pretty inefficient for large objects. What does actually happen when I call slot- ? I suppose that this always operates on the object in sys.parent() of slot- and never creates a copy of the specified object. and I set my validity checker to make sure that the length of the string is the number in b. Now that basically means that I can never change the string (except to other strings of the same length) if validity checking happened after every change. I somehow need changing both a and b to be instantaneous (which they currently are not). We have not really gone far enough down that path yet to know what the right thing is, but we are working on it. So for now validity checking occurs at a few specific points and if/when you ask for it. What about access control ? The docs state it isn't implemented yet. If there was something similar to C++ one could set critical slots to private and only allow access and assignment via (replacement) methods. At first sight, this seems feasible and shouldn't cost much performance. Another approach might be an (optional) validation function for each individual slot or for groups of slots that doesn't need to validate the whole object but only changes that may occur in conjunction with a single slot or group of slots. Of course, efficiency issues are more likely to occur in this scenario. The @- operator seems to call slot- by default, maybe I can overload slot- for my class and implement this kind of validation on my own ? I guess some tricks will be necessary here to prevent that slot- is called recursively if the validation function for one slot attempts to make an assignemt to another slot. So if I don't find a feasible solution in the meantime, the best way would be writing wrappers for those slots that need validation and tell the users to use those instead of changing the object directly ?

[R] coupled statistical models
Can someone point me to the appropriate functions for fitting multiple statistical models that are coupled to each other. The data are measurements of salinity s and temperature t at stations id and pressures at p as well as surface elevations h at stations id. The problem is, for any new station, to estimate s at all p, given t at all p and given h. If h is ignored, the for each p, there would be an independent model like rlm(s~t+I(t^2)). No problem. (I have been using a loop, but I think they can be computed simultaneously using lm(s~as.factor(p)/(t+I(t^2))-1). However, rlm(s~as.factor(p)/(t+I(t^2))-1) does not converge!) The h data couple the models. Surface elevation reflects the water's specific volume at each depth (pressure). The volume vp (p to indicate pressure) depends on s,t, and p, and h is essentially a sum over the volume at each p. When the individual models are computed, coefficients should be chosen so that this is satisfied. How to do this in R? Without the coupling the least-squares formulation would seek coefficients a_p and b_p to minimize: sum_p(sum_p((s_id,p - a_p t_id,p + b_k)^2)). Minimization at each p is independent. With coupling, there would be an additional term: sum_id((sum_p(vp)-h_id)^2) where vp is a function of a_p t_id,p + b_k and of t_id. The functions for vp are nonlinear, but if necessary with some work it should be possible to get a linear function that is good enough. Also, not all stations have values at all pressures.

Re: [R] Trouble plotting with factor

First, can I give you some example data? Here is a column of names for age groups: agegroups - c( 15-19, 20-24, 25-29,30-34, 35-39, 40-44,45-49,50-54,55-59,60-64, 65-69, 70-74, 75-79, 80-84, OVER) Here is an index for driver's license ownership in each age group: fracld 0.4914204 0.9752746 1.0864465 1.0555984 1.0631969 1.0738725 1.0971969 1.0657212 1.0217373 0.9761226 0.9043233 0.9045744 0.8573243 0.7889182 0.5217992 I want to take several similar columns of numbers and put them into a single line plot, one line for each column. I can get a graph with the inside part that looks roughly like I want if I just do: plot(fracld,type=l) The horizontal axis, of course, is just the sequence from 1:15, not the age labels. That's no good. But, If I try plot(as.factor(agegroup), fracld, type=l) the plot does not have the line I want, but rather only flat steps showing the values. It does have a nice looking horizontal axis, though, showing the age groups. So I think to myself I'll outsmart them by adding the lines after creating the plot, but if I do this plot(agegroup,fracld,type=n) The step markers still appear. So if I want the tick marks and value lables on the horzontal axis, there is apparently no way to plot lines? What to do? Paul, I did not see any responses come through yet on this, so I don't know if you got anything offlist. I do not know how your data is structured, but one approach, if your data is in a matrix, with the numbers being the columns and the agegroups being the rownames, is the following: # Create the agegroups agegroups - c(15-19, 20-24, 25-29,30-34, 35-39, 40-44,45-49,50-54,55-59,60-64, 65-69, 70-74, 75-79, 80-84, OVER) # Create the first column fracld - c(0.4914204, 0.9752746, 1.0864465, 1.0555984, 1.0631969, 1.0738725, 1.0971969, 1.0657212, 1.0217373, 0.9761226, 0.9043233, 0.9045744, 0.8573243, 0.7889182, 0.5217992) # Now create two additional columns for the example # 'fracld2' won't make sense real world since many vals # will be 1.0 fracld1 - fracld - 0.25 fracld2 - fracld + 0.25 # Create the matrix df - cbind(fracld, fracld1, fracld2) # Set the rownames rownames(df) - agegroups df fracld fracld1 fracld2 15-19 0.4914204 0.2414204 0.7414204 20-24 0.9752746 0.7252746 1.2252746 25-29 1.0864465 0.8364465 1.3364465 30-34 1.0555984 0.8055984 1.3055984 35-39 1.0631969 0.8131969 1.3131969 40-44 1.0738725 0.8238725 1.3238725 45-49 1.0971969 0.8471969 1.3471969 50-54 1.0657212 0.8157212 1.3157212 55-59 1.0217373 0.7717373 1.2717373 60-64 0.9761226 0.7261226 1.2261226 65-69 0.9043233 0.6543233 1.1543233 70-74 0.9045744 0.6545744 1.1545744 75-79 0.8573243 0.6073243 1.1073243 80-84 0.7889182 0.5389182 1.0389182 OVER 0.5217992 0.2717992 0.7717992 # Now use matplot() to plot each column # Do not plot the axes matplot(df, type = l, axes = FALSE, xlab = Age Group, ylab = Proportion DL Ownership) # Create the X axis, specifying 15 tick marks # and using rownames(df) as the labels axis(1, at = 1:nrow(df), labels = rownames(df)) # Now draw the Y axis with defaults axis(2) # Put a box around the whole thing box() BTW, this is also using FC1 and R 1.8.1 Patched.
