...t graphics device if no plot exists there yet, but adds lines to the existing plot if a plot is already there. How can I do this? It seems to me that the exists() function might be co-opted to do this, but it's not obvious how.

...\beta_{2,1} = \beta_{3,2} that is, that the effect of X_1 on the logit of Y_2 is the same as the effect of X_2 on the logit of Y_3. Is there an existing facility or package in R for doing this? Would multinomRob fit the bill?

...be able to clarify, and/ or suggest a possible workaround? It's an unfortunate conflict because running JAGS models is one of the most computation-intensive operations that I have in my .Rnw document. Best & many thanks in advance.

...ught should work, but this gives me an error: > wfreq1(my.lexicon,'the') Error in eval(wfreqs[word], envir = lexicon at e) : object 'wfreqs' not found Any advice would be much appreciated!

...e i,j row,column information into the splom panel function, but it is not trivial because panel.pairs() calls several lattice-internal functions which are not exported. So if there is a better way, I would be grateful to know!

...operly. The cairo graphics device does handle these characters properly. Thus I'd like to be able to instruct Sweave to use cairo (either sometimes or always) to produce graphics when it processes R code. Is this possible?

While I have been able to install rjags on my Windows computer, oddly I have been unable to install rjags successfully on my 64-bit Linux compute server (etch, Linux kernel 2.6.18). I am required to specify the JAGS module directory upon installation; when doing this within R, I get:

I'm interested in a version of tapply() that operates with shingles instead of factors. For instance: x <- c(1,1,2,2,3,3) y <- c(1,1,1,0,0,0) s <- shingle(x,intervals=cbind(c(0.5,1.5),c(2.5,3.5))) # the following function should exist! tapply.shingle(x,s,mean) # returns the vector c(0.75,0.25) I've written such a function as follows: tapply.shingle <-

Hi Rob The stream format has nothing to do with your audio files. I probably have 70% MP3's and 30% Ogg Vorbis files, and 1 or 2 WAV files for jingles on my hard drive. I only encode new CD's to Ogg Vorbis. But my station is streaming in AAC+ format, and I have also streamed in Ogg Vorbis format simultaneously. There is no way I would bother streaming in MP3 format. It's 15+

I have a data frame with Cyrillic text that I would like to be able to view under RGui. Unfortunately I can't figure out from the manuals how to make this happen -- can someone point me in the right direction? Thanks, Roger Levy
