[R] ifelse on data frames

[Using R 2.2.0 on Windows XP; OK, OK, I will update soon!] I have noticed some undesirable behaviour when applying ifelse to a data frame. Here is my code: A - scan() 1.00 0.00 0.00 0 0.0 0.027702 0.972045 0.000253 0 0.0 A - matrix(A,nrow=2,ncol=5,byrow=T) A == 0

Re: [R] Extracting R plots from MS Word

Just a note to say what I did. I think that the results were OK but I have yet to hear from the journal. 1. I saved the Word document under another name. 2. I deleted all the contents of the document except the target graphic. 3. I printed to file yielding a .prn file. 4. I changed the extension

[R] Extracting R plots from MS Word

Hi, I am revising a paper that I am a co-author of. The figures are plots generated from R but at the moment I do not have the R code that generates them. As this is time critical I would like to slightly abuse the list by asking whether anyone knows how to extract from MS Word into a

Re: [R] Extracting R plots from MS Word

Thanks to all those who responded to my request about extracting R plots from MS Word. I decided to try Gabor Grothendieck's second suggestion and saved the Word document as html. (I may yet try some of the other suggestions.) Saving the .doc as .htm indeed produced a folder with many of the

[R] Bootstrap ICC estimate with nested data

I would appreciate some thoughts on using the bootstrap functions in the library bootstrap to estimate confidence intervals of ICC values calculated in lme. In lme, the ICC is calculated as tau/(tau+sigma-squared). So, for instance the ICC in the following example is 0.116:

All, I've encountered the same problem as others who have posted under the same subject. I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can

Re: [R] model-based clustering

The list could probably be more useful if you gave more details about your data and the problem. I have written a bit of R code myself for fitting a finite mixture of univariate Poissons by EM and found it very simple to program in R. I suspect that your problem is multivariate, but that should

RE: [R] Using files as connections

I nearly forgot to thank Andy Liaw and Tony Plate for their help with this problem. BTW Andy's method does run faster than the natural fix-up of my original code. Murray Jorgensen You are using the connection the wrong way. You need to do something like: fcon - file(c:/data/perry/data.csv,

[R] Using files as connections

I have been trying to read a random sample of lines from a file into a data frame using readLines(). The help indicates that readLines() will start from the current line if the connection is open, but presented with a closed connection it will open it, start from the beginning, and close it when

[R] matrix subscripts in replacement

I'm reluctant to draw the S-PLUS and R comparison (these are different programs after all), but could someone tell me why the following matrix substitution works in S-PLUS, but not R. I'm curious because matrix substitution is a really slick way to cleaning up columns of data in data frames. For
