[R] image 256 x 920 data points too slow
Dear R gurus, I'm trying to visualize a matrix 256 x 920 using image(), but i find the display too slow (~ 1 minute –– admittedly, my iBook G4 isn't very fast). The aim is not to get a good resolution image, but rather have a quick look at the matrix.

Is there an easy option for this purpose in image(), or possibly the lattice equivalent?

Re: [R] formatting a list
Hi Jim,
thanks a lot. It works, however - my other problem is that I need to
transpose the original table before reading it into the list because the
data come from Excel and it can't handle 7000 columns. I could read it
in R transpose end write into a new tab delim file and then read it back
in, but I would think that there might be a way in R to do both.
Would you know about the way?

1. Do you appreciate the difference between ifelse and if ? What are
you actually trying to do - in this context, ifelse would usually be
more sensible but as you've not said what you want to do, it is
difficult to guess.

This error message makes it clear that there is a syntax problem. In
fact, look at the lefthand column of characters and you should see
what the problem is
3. R is interpreting your code as two separate expressions because you

Re: [R] Error in if loop
Dear Mark,
Thanks for this. Can you please explain me what is the difference between

generally if there is more than one syntax within the 'if' I use 'if' loop
otherwise I use 'ifelse' loop. Is it the only difference between them?

Re: [R] formatting a list
What is it that you want to do? The 'scan' statement give you a list
of length 7000 with 19 entries each. Do you want to create a matrix
that has 7000 rows by 19 columns? If so, then you just have to take
the output of the 'scan' and do:
x.matrix - do.call('rbind', x) # gives 7000 x 19 matrix.
So I am still not sure exactly what your input is and what you want to
do with it.

Re: [R] formatting a list
That is what I thought and that is the format that the 'scan' approach
should provide. I was just confused when you said that you were going
to have to transpose it, write it and then read it back in for some
reason. I understand that Excel can not handle 7000 columns, but was
wondering where that came into play.

Hi Jim,
thanks a lot. It works, however - my other problem is that I need to
transpose the original table before reading it into the list because the
data come from Excel and it can't handle 7000 columns. I could read it
in R transpose end write into a new tab delim file and then read it back
in, but I would think that there might be a way in R to do both.
Would you know about the way?

Hi,
I am new to R and need to read in a file with 19 columns and 7000 rows
and make it into a list of 7000 lists with 19 items each. For a
simpler case of 10 by 10 table I used x -scan(file,
list(0,0,0,0,0,0,0,0,0,0)), perhaps clumsy, but it did the job.
However with the large 19x7000 (which needs to be transposed) I am not
sure how to go about it.
Coudl somebody suggest a way?
Thanks,

[R] [R-pkgs] ggplot2 - version 0.5.6
ggplot2 === ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and avoid bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce complex multi-layered graphics. Find out more at http://had.co.nz/ggplot2, and check out the over 500 examples of ggplot in use. Changes in version 0.5.6 Improved error messages and other notifications: * all geoms and position adjustments should now give an informative error message when required aesthetics are missing * better error messages if data not a data frame, or mapping not created by aes or aes_string * better errors for qplot when variables missing or data invalid * better error if somehow you are missing necessary scales * stat_bin informs you of the default choice of binwidth * stat_smooth gives helpful error messages for common problems * printing a geom now displays the data set that it uses (if not the default) Other improvements: * colour and fill legends now surround by background plot colour * can now draw arrow heads with geom_segment, and have added an example demonstrating drawing a vector field * density plots should always include 0 on y axis * default boxplot outlier changed colour to black * stat_smooth supports categorical variables a little better * implemented hash methods for all ggplot objects. This is the first step in making it easier for me to compare all examples between versions for quality control purposes New data: * seals, contributed by David Brillinger and Charlotte Wickham, used for vector field example Bug fixes: * geoms hline, vline and abline now all work correctly when a grouping variable is used * block histograms (where individuals are identifiable) now work correctly * all ggplot objects should now print properly from the command line * fixed bug in geom_path when only 1 point * segments geom now works correctly for more coordinate systems * order variables in scatterplot matrix by order of variables in data.frame * geom_density deals with missing values correctly when displaying scaled densities * fixed bug in calculating categorical ranges * fixed bug in drawing error bars Subtractions * now relies on R 2.6 * removed grid.gedit and grid.gremove, and code replaced by grid.ls -- http://had.co.nz/ ___ R-packages mailing list [EMAIL PROTECTED] https://stat.ethz.ch/mailman/listinfo/r-packages __ 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] Format of a data frame
The goal is to smooth a scatterplot using the LOESS locally weighted regression program and a gam. There are 156 points. Thus x can have the value 1, or 2, etc., up to a maximum of x = 156. The y values are random, with a Poisson distribution, or the next thing to it. After reading in the data, I was able to generate a model, named mod, as follows: mod - gam(y~lo(x), family=poisson, x = TRUE) Next, I want to look at some values of the fitted curve: Specifically x =1, x = 2, and x = 3. Upon looking up predict.gam, I see the following: Usage predict.gam (object, newdata, type, dispension, se.fit = FALSE, na.action, terms ...) One of the arguments of the function is named newdata. I see: newdata A data frame containing the values at which predictions are requested. [snip] Only those predictors, referred to in the right side of the formula, need be present by name in newdata. I am having difficulty figuring out the format of the data frame. For example, how many columns should it have? Should it have a column for the three values of x? Probably there is a rather standard format for data frames, but I am having trouble looking it up. Perhaps some one would point me to the place in the documentation where this is discussed.

Re: [R] Format of a data frame
If you look at the example for predict.gam, it should be clear that the data frame has a column(s) for the value(s) you want to predict for: newd - data.frame(x0=(0:30)/30,x1=(0:30)/30,x2=(0:30)/30,x3=(0:30)/30) pred - predict.gam(b,newd) head(newd) x0 x1 x2 x3 1 0. 0. 0. 0. 2 0.0333 0.0333 0.0333 0.0333 3 0.0667 0.0667 0.0667 0.0667 4 0.1000 0.1000 0.1000 0.1000 5 0.1333 0.1333 0.1333 0.1333 6 0.1667 0.1667 0.1667 0.1667 On 10/21/07, Thomas L Jones, PhD [EMAIL PROTECTED] wrote: The goal is to smooth a scatterplot using the LOESS locally weighted regression program and a gam.

[R] Newbie help: Data in an arma fit
I'd like to fit an ARMA(1,1) model to some data (Federal Reserve Bank interest rates) that looks like: ... 30JUN2006, 5.05 03JUL2006, 5.25 04JUL2006, N lt; here! 05JUL2006, 5.25 ... One problem is that holidays have that N for their data. As a test, I tried fitting ARMA(1,1) with and without the holidays deleted. In other words, I fit the above data as well as this data: ... 30JUN2006, 5.05 03JUL2006, 5.25 05JUL2006, 5.25 ... and the ARMA coefficients came out different. My question is: Should I delete all the holidays from my data file? What exactly does R do with the N values in the fit for the ARMA coefficients? As a related question, the weekends don't have entries (since the FRB is closed on all weekends). Does the fact that my data is not regularly spaced pose a problem for ARMA fitting?

Re: [R] Input appreciated: R teaching idea + a way to improve R-wiki
Bill, very interesting comment. However, do you believe that by posting these tutorials on a wiki they could, even if initially faulty, be improved by the community over time?

While the principle seems OK, in a optimistic sort of way, you may be a little disappointed by the outcome. Some will likely be superb, useful, well written and accessible. Others, I suspect, will fall short of this ideal, with some falling a fair way short. That's the way students learn, after all. They should use these exercises to straighten things out in their own minds, and some of them seem to have rather twisted ideas, at least initially, even at graduate-level. Some people argue it's useful to see the learning process in action, and some books I could mention seem to be written this way - but they don't get very good reviews. I just think there is a real danger here of giving misleading and inefficient teaching materials a spurious cloak of legitimacy, even if there are disclaimers all over it. I see a need to be very cautious about this, in other words.

I have a teaching idea that might also help improve the R wiki page... I wanted to know what you all thought of it and wanted to solicit some advice about doing it. During the latter part of the course, students will choose a topic of interest (e.g., hierarchical linear modeling), and show how to achieve it in R. They would present their findings to the class, and would also be responsible for writing a concise but well-written How To manual on the topic. These would be ~ 5-10 pages and would include basic background of the statistical procedure and a commented example with code in R. The goal would be for these to read like Baron Li's Notes on the use of R for psychology experiments and questionnaires. Originally I was going to post these as PDFs on my own web-page and let them grow into a compendium of how-to manuals as I teach this course over the years. However, perhaps a better idea, and one that probably benefits more people, is to have my students post their short manuals (not as PDFs but rather typed in) on the R-wiki page. Does this seem like a good idea to folks? Another question has to do with how barren the current R wiki page is... is it still being actively developed or has the community given up on it? Finally, any thoughts on where on the R-wiki site we should post our How To manuals? The tips and tricks section seems to barely be more than snippets of conversations from this list-serve (often sans the context). My guess is that the Guides section is where these should go.

Re: [R] loess coefficients output
loess() is a 'local' fitting procedure, which means that it fits a different regression at each prediction point. (In principle, for there are computational short cuts: see ?loess.control.) Since each fit is only used for a single prediction, its coeffiicients are not of interest and not made available.
