Re: [R] Plot nls line on plot?
Hi Doug, you can add the fitted curve using the following general paradigm: ## Plotting the data plot(p~z) ## Defining grid of z values ## (100 values ensures a smooth curve in your case) zValues - seq(min(z), max(z), length.out = 100) ## Adding predicted values corresponding to the grid values lines(zVal, predict(fit, data.frame(z = zValues))) Christian __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] Parameters of Beta distribution
In article 5df5755d-a376-439a-b7f2-9901441db...@comcast.net, dwinsem...@comcast.net says... In insurance situation there is typically a cap on the covered losses and there is also typically an amount below which it would not make sense to offer a policy. So a minimum and a maximum are sensible assumptions about loss distributions in may real modeling situations. But a continuous distribution would then not be a reasonable distribution. More precisely, one would typically have a mixture of a continuous and a discrete distribution, with some point probability mass at the max. -- Karl Ove Hufthammer __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] Substituting the extracted coefficients into the formula, exctracted from the result of nls()
Dear all, Here I come with another stupid question. Suppose I want to use nls() to fit a series of data (here modelled by generated points), then plot the points and the fitting curve. I figured out some way of doing it: x - runif(1:20, 0, 10) y - 0.1*x^2 - rep(3, length(x)) + rnorm(length(x), sd = 0.5) yfit - nls(y ~ a*x^2 + b*x + c, start = list(a = 1, b = 1, c = 1), trace = TRUE) plot(x, y) curve(coef(yfit)[1]*x^2 + coef(yfit)[2]*x + coef(yfit)[3], 0, 10, add = TRUE) However, this code is rather fortranesque, and most likely there exists a much more elegant way in R/S, something like abline() which exists for straight lines. Since both the formula and the coefficients are available as a result of nls() (here as formula(yfit) and coef(yfit)), I thought there ought to be a way something along the following lines: f - substitute(formula(yfit), as.list(coef(yfit))) curve(f, ...) However, this snippet of code doesn't work. Am I thinking into the correct direction at all? Thanks in advance.

However, I am finding that whilst the trendline is correctly displayed and representative of the data portion I've chosen, the line continues to run beyond this data segment and continues until it intersects the vertical axes at each side of the plot. How do I display the line so that it only runs between point 36 and 45 (as shown in the example above) as doesn't continue to display a line throughout the rest of the plot space?

I would would have to increase the returning call:

What I would like to be able to do is pass x the list of lists and have it
return the required points.
Anyone have any clues on how to get over this hurdle?
Thank you

[R] Any reference to Tukeyline algorithm?
Hi, I am using line function to plot the line. And I would like to understand Tukeyline algorithm. Since, the line function is calling the Tukeyline algorithm(which is compiled code) using foreign function interface, I am not able to look into the source code of this algorithm.

Re: [R] Substituting the extracted coefficients into the formula, exctracted from the result of nls()
If you want curve with substitute(...), you can try something about like this: f - eval(parse(text = paste(substitute(, formula(yfit)[3], , as.list(coef(yfit))), sep = ))) curve(f, ...) 2009/10/9 Henrique Dallazuanna www...@gmail.com: Try with predict: plot(x, y) lines(0:10, predict(yfit, list(x = 0:10))) 2009/10/9 Primoz PETERLIN primozz.peter...@gmail.com: Dear all, Here I come with another stupid question. Suppose I want to use nls() to fit a series of data (here modelled by generated points), then plot the points and the fitting curve. I figured out some way of doing it: x - runif(1:20, 0, 10) y - 0.1*x^2 - rep(3, length(x)) + rnorm(length(x), sd = 0.5) yfit - nls(y ~ a*x^2 + b*x + c, start = list(a = 1, b = 1, c = 1), trace = TRUE) plot(x, y) curve(coef(yfit)[1]*x^2 + coef(yfit)[2]*x + coef(yfit)[3], 0, 10, add = TRUE) However, this code is rather fortranesque, and most likely there exists a much more elegant way in R/S, something like abline() which exists for straight lines. Since both the formula and the coefficients are available as a result of nls() (here as formula(yfit) and coef(yfit)), I thought there ought to be a way something along the following lines: f - substitute(formula(yfit), as.list(coef(yfit))) curve(f, ...) However, this snippet of code doesn't work. Am I thinking into the correct direction at all? Thanks in advance.

Re: [R] proto and get()
In further offline discussion with the poster it was explained that
the purpose of this is to display the icon object and not to return an
instantiatedProtoMethod which was what the code was attempting to do.
That is in proto, g$icon is not the icon object. It is the icon method
instantiated with the g object, essentially a currying operation in
which the object is plugged into the first arguement of icon and the
resulting function (no longer a method since its now been
instantiated) returned. To get what the poster desires, namely the
icon object itself, one would do this instead of g$icon:
with(g, icon)

Re: [R] odfWeave XML error in post-processing
Hi Rob. Without the file content_1.xml or any information from the R call stack (e.g. options(error = recover) and then run the command and dynamically explore the state of affairs when the error occurs), there is no way for us to know what the problem might be. Somehow, the XML parser appears to be seeing a token and token is not a legitimate XML element name. It may also be seeing apos; which would identify an XML entity. Assuming that this is what the XML parser is seeing, the question is how they got into the document. So we need more to start diagnosing the problem. D.

Re: [R] Problems with code containing a for loop
Because you missed your closing parens in the text function call. The closing
parens is closing the paste function, you need one more. I don't know what
you're trying to do here, but I am guessing there's a faster way?

[R] For loop isn't working correctly
Hi. With your help, I've fixed the errors in my for loops.
But now, the for loop isn't working correctly. There should be a plot,
but there's no plot when I run the for loop..

for(i in 1:6){ #6 letters
for (j in 1:3) { #3 numbers

fn = paste (i,j,k,.bmp,sep=)

axes=FALSE, ylab=, xlab=)
text(0.5,0.5, labels = paste(letters[i], +,
numbers[j],=, letters [i+j+k]))
dev.off()
}
}
}
Can somebody see why this isn't running correctly?

[R] wrong plot with fda or lda?
Hi, I have a strange behavior of plot function when trying to plot a discriminant analysis obtained by fda. I'd attached the data for reproduction. I made the same analysis (linear discriminant analysis) but using lda and fda (default args, using polyreg). The resulting coefficients and trace proportions for the two analysis are the same, that's good, but if you plot the two analysis the graphs are very different. Plotting the results of lda function gives much more overlapping of points from different groups than using fda. If you make: libray(MASS) library(mda) read.table(data, header=T) - data data[,1] - grp data[,2:24] - X #Linear discriminant analysis using fda fda(grp ~ ., data=X) - FDA plot(FDA) #Linear discriminant analysis using lda lda(grp ~ ., data=X) - LDA plot(LDA, col=palette()[grp])# Very different results #Same coefficients coef(FDA) coef(LDA) Regards, __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] Trendline for a subset of data
You are emitting weird hex-stuff from your mail client. And from what I can tell that is not a reproducible example even if hex-ation problem gets fixed. There is a worked example in segments.

However=2C I'm having troubl= e getting it to work - this is probably due to me misunderstanding the docu= mentation for this command. The plot section of my script appears as follows: test3 - 36:45 plot(data_means=2C type=3Db=2C pch=3D4=2C ylab=3D=2C xlab=3D=2C xaxt= =3Dn=2C yaxt=3Dn=2C col=3D3=2C ylim=3Dc(250=2C380)) abline(lm(data_means[36:45] ~ test3)=2C lty=3D2) As you can see=2C I cannot see anything. If you are under the impression that there should have been an attachment, then (re-?)read the Posting Guide on that topic. I'm only plotting points 36 to 45 from the object 'data_m= eans'. This intentionally results in much white space along the x- axis unti= l point 36 is reached. However=2C when inserting the trendline=2C this runs= along the entire length of the x-axis instead of just through points 36 to= 45. Ideally=2C a line which slightly overshoots the data subset would look= the best=2C but one constrained to the extents of the 36:45 would also do = the job just fine.

(and overshoots a= t either end very slightly=2C if possible=2C rather than running along the = entire length of the x-axis). The basic strategy would be to calculate the x and y coordinates of the two points at the end of the desired segment and then say segments( x[1], y[1], x[2], y[2] ) Many thanks again=2C Steve CC: r-help@r-project.org From: dwinsem...@comcast.net To: smurray...@hotmail.com Subject: Re: [R] Trendline for a subset of data Date: Fri=2C 9 Oct 2009 09:27:43 -0400 On Oct 9=2C 2009=2C at 5:50 AM=2C Steve Murray wrote: Dear all=2C I am using abline(lm ...) to insert a linear trendline through a portion of my data (e.g. dataset[=2C36:45]).

[R] Use R -- term and logo copyright?
Dear list, I would like to start some R workshops at King's College London, and to do so, I would like to use the Use R! logo at http://www.agrocampus-ouest.fr/math/useR-2009//useR%21%202008_fichiers/useR-middle.png Since it seems to be difficult to get a shell account at KCL, I also went ahead and registered use-r.org.uk and am starting to put together a website at kcl.use-r.org.uk. I really like the Use R! slogan, which seems to be used by the R user conferences and Springer (the latter without the exclamation mark). Even more, I really *really* like Use R! logo. I think it is very elegant indeed! Kudos to whoever designed it. However, I'm completely in the dark about copyright issues of the logo and the slogan. Can I use (a) the logo and/or (b) the slogan for the KCL R workshops? I think it is quite clear from my website that this is neither about the Springer book series nor about an R user conference. I enquired with the agrocampus-ouest.fr website about the logo but was pointed to r-project.org and the R development core team. I thought in that case it might be best to ask here to have the answer publicly available -- sorry if I overlooked the information online somewhere.

Re: [R] gregmisc library (Mandriva)
Hi You may find that you need to use the compilation tools. I gave up on using R from Mandriva repositories as the R base is usually out of date and the selection of packages available depends on the interests of those who produced them. If I knew how rpm spec files worked I might do something about it for my interests. Of course if the package is simply R code with no C, C++, Fortran needing compiling, then unpacking the source in your library location will do, though you may need to check dependencies. I do like Mandriva, but for programs like R using install.packages() and having the relevant devel-packages enables you to keep up to date.

[R] lm output
Hi All I am running a linear regression using the lm object. In the event that my independent variable is the same across all observations the regression slope is returned as an NA. For example, if I have the following y=c(10,12,17) x=c(5,5,5) lm = lm(y~x) produces the following Coefficients: (Intercept)x 13 NA Other than post-processing the results, is there a way to output the slope as 0 rather than NA?

Re: [R] lm output
That comes out as an NA because X'X is not invertible because it is not full rank (one row/column is a linear combination of the other(s)). And that means there is no unique solution to the system. y=c(10,12,17) x=c(5,5,5) X=cbind(1,x) X t(X)%*%X solve(t(X)%*%X) Therefore, nope, there is now way to make this come out as a zero, because it fails the very assumptions of regression analysis.

Thanks Pete You should post-process! To incorporate such a thing into the function lm() itself would be an arbitrary resolution of an indeterminate situation, and would not be appropriate for a general-purpose function. Your situation is, graphically, 17 +* | 15 + | | 12 +* | 10 +* | | | | 5 +++ 0510 Any line whatever through the point (5,13) will fit the three points as well as any other, so the slope is indeterminate.[*] You have decided that you would like it to be zero, but that is an arbitrary decision! [*] Note that a vertical line (with slope +/- Inf) does not resolve the indeterminacy, since, although it goes through all three points, you do not know which point[s] on the line to use in evaluating the error -- the difference between a point on the line with given value of x and the y-value on the line corresponding to x -- because all points on the line qualify as potential y values, since they all have the same value of x. Since the slope is indeterminate, it is NA (that is what NA means). It arises numerically because the calculation of the slope is (N*sum(x*y) - sum(x)*sum(y))/(N*sum(x^2) - sum(x)^2) which is 0/0 -- likewise NA. Hoping this helps, Ted.

Re: [R] lm output
Daniel Thanks very much for the reply. If the data fails the underlying assumptions of regression wouldn't it make sense to suppress all the output and not just the slope coefficient? Incidently, if I run this simple example in Excel it returns the slope as 0. Intuitively, this makes sense to me ... the best estimate of y would be its mean for any value of x.

Intuitively, this makes sense to me ... the best estimate of y would be its mean for any value of x. On the contrary -- your data give you no information whatever about the value of y at any value of x other than x=5. So, given your data, if you want to predict the value of y for some other value of x, you can choose whatever value you like -- hence the indeterminate slope. And this is where the statement made by Excel is grossly misleading: telling you that the slope is 0 would make you adopt the same value (mean(y) = 13) for any value of x, and you have no basis whatever for doing so.

Re: [R] plot the same types of graphics on the same R graphic device
Hi Carol, It isn't at all clear exactly what you are trying to do, but you might want to read the help for either points() and lines() [to put more than one data pair on a single plot], or for par, specifically mfrow and mfcol, or for layout [to put more than one plot on a single device window].

[R] regressions on large dataframe: speed?
Dear R Helpers,
I have a pretty large dataframe (150,000 variables, 10,000 entries for
each) and have to run a regression on each of the variables. Recorded are
the pvals.
I wrote a function and use sapply. The function looks something like this:
calcpval-function(x){
modela - lm(apples~age,data=m)
modelb - lm(apples~age+ageSquared,data=m)
modelc - lm(apples~age+ageSquared+bmi,data=m)
p_main - anova(modela,modelb)$P[2]
p_main_i - anova(modela,modelc)$P[2]
p_i - anova(modelb,modelc)$P[2]
return(c(p_main,p_main_i,p_i))
}
This whole thing is terribly slow... I observed that it's faster when
breaking down the file. But other suggestions could you please make to make
it run faster (say days instead of weeks).
Thank you and best regards, Georg.

Re: [R] odfWeave XML error in post-processing
Just so we complete (partially) the web-record... Some further hunting determined that the apos was an apostrophe - obvious only in retrospect! Removal of this character has resolved the Entity errors, but not the xmlParseStartTag: invalid element name errors. I had assumed that the two errors were dependent, but they are not. odfWeave does have some ability with its translate command to address some XML/OO special characters, but I have not explored this facet of odfWeave yet, and I was a bit surprised that the use of this common grammatical mark generated an error, but.. Now, in search of a cause for the invalid element name error(s). Thanks to Duncan for his help. Duncan Temple Lang wrote: Hi Rob. Without the file content_1.xml or any information from the R call stack (e.g. options(error = recover) and then run the command and dynamically explore the state of affairs when the error occurs), there is no way for us to know what the problem might be. Somehow, the XML parser appears to be seeing a token and token is not a legitimate XML element name. It may also be seeing apos; which would identify an XML entity. Assuming that this is what the XML parser is seeing, the question is how they got into the document. So we need more to start diagnosing the problem. D.

In the event that my independent variable is the same across all observations the regression slope is returned as an NA. For example, if I have the following y=c(10,12,17) x=c(5,5,5) lm = lm(y~x) produces the following Coefficients: (Intercept)x 13 NA Other than post-processing the results, is there a way to output the slope as 0 rather than NA?

[R] Running R scripts from a GUI interface
It appears several that of my scripts are beginning to reaching maturity, so I am curious if it is possible to add an external GUI to run the scripts from this simplified GUI interface. The scripts are fairly rudimentary so the GUI only needs a few radial buttons and a could of numeric fields. I am curious if there is a typical approach for developing a GUI to run R scripts or to export R scripts in a DLL or other format so that they can be run from such a GUI. I also have not settled on a GUI development language so any suggestions there are also very much appreciated. Thank you again for any feedback and insights, especially if there is a blog or book that covers these topics. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] How to get last status change, ctime on Windows?

Help file says that on Unix this is 'last status change' and on Windows 'creation time'. No, that is not what it says. It actually says What is meant by the three file times depends on the OS and file system. On Windows 'ctime' is the creation time. The POSIX standard 1003 uses these terms, and its definitions are at http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_07 but of course Windows does not claim to be POSIX-compliant. So the help page is answering Duncan's question What does last status change mean on Windows? by saying that on Windows 'last status change' means 'creation time'. Unix-alikes differ in what they say about ctime, but for example Linux says The field st_ctime is changed by writing or by setting inode information (i.e., owner, group, link count, mode, etc.). Windows does not have inodes nor most of those concepts ... so we need to look at what its system documentation (MSDN) says it returns in the field st_ctime of its 'stat' system call. Other sources suggest that MSDN is wrong and st_ctime returns 'creation time' only on Windows' native file systems: but that possibility is covered by the two sentences quoted. -- Brian D.
