Tiger's rsync anomalies I'm trying to sort out some anomalies using rsync locally. Booted to Volumes/LaCie_Disk_A I create a full direct clone with: sudo asr -erase -source /Volumes/Mirrored_HD_Set -target /Volumes/LaCie_Disk_B then boot to it and check it out. Then booted back to Mirrored_HD_Set I do a little other work (i.e. some files are changed). Then for a differential

Is it possible for S4 to (continue) dispatch to a class created during dispatching? The code below doesn't work; is this not possible or have I ommitted something? Concept was to create a SEXP with R_AllocatePtr, give it a class attribute, and continue dispatch. Example code below omits multiple parameters that can be different types. Essentially, any parameter would be converted to an

Hi all, I've just installed R on my Mac & PC. The base demo run fine.. But I'm encountering several pb with some packages (installed using CRAN binaries using the menu) - Lattice: > demo(lattice,package='lattice') demo(lattice) ---- ~~~~~~~ Type <Return> to start : > require(grid) [1] TRUE > old.prompt <- grid.prompt(TRUE) > old.settings

R-helpers, Is there an easy way to call an external (C) program using .C or .Call without including the code in a package. I know how to do it using system(), but that doesn't seem to be a permanent or portable solution. Initially I tried: .Call('filepath.to.c.function', arg1) and got this error: Error in .Call("filepath.to.c.function", "arg1", :

Dear list, I'm trying to understand the graphical parameters by a systematic exploration of the par() function (if you are interested by the result it's here http://pbil.univ-lyon1.fr/R/fichestd/tdr75.pdf, the comments are all in french but it's pure R code under Sweave). I have a problem with par(tmag) illustrated by the following code:

I have a number simple R functions written for the biologists I work with. These functions will evolve, and the documentation will get steadily better. I hope to put them in a package on a local webserver, along with lots of help files, so that the users can easily update their installation. The functions are pure R, with no compiled code, but alias, I cannot figure out how to build this

I couldnt find a previous posting on this in the archives, maybe it has already been mentioned. If you use a calculation to generate n observations in random number generators and you don't round to the nearest integer you may be generating n-1 numbers not n numbers as you thought depending on the storage precision of the calculation. e.g. > m <- 1000 > pi0 <- 0.9 >

hi everybody, I noticed the following: in one of my scripts 'layout' is used to generate a (approx. square) grid of variable dimensions (depending on no. of input files). if the no. of subplots (grid cells) becomes moderately large (say > 9) I use a construct like ###layout grid computation and set up occurs here### ... opar <- par(no.readonly = T);

Dear List, I have been trying to use library sm to do density estimation on a 3D dataset. I am using the current MacOS X binary of sm from CRAN. If I do this on a 2D dataset, sm.density returns a list including the component "estimate" which contains the density estimate over a uniform grid. When doing this with 3D data, although I get a nice plot (even when I don't ask for one),

Hi, My problem does not happen all the time, nor with all files I save to csv format. I can send my test file (format rda or csv) to whoever would like to replicate (and hopefully explain) my problem. In short, I have a dataset with mostly numerical variables. One of my variable is called pfi2 and is definitely numerical, as shown by this: > summary(test$pfi2) Min. 1st Qu. Median

I have been running R CMD check for the first time on of our own packages, which otherwise builds, installs and runs just fine. The package depends on package akima and suggests package multtest; suggesting multtest is indicated because a) it loads a lot of other Bioconductor packages, very slowly, and b) it is only needed for one specific subroutine, which executes require(multtest)

Hi, I'm trying to add points to 2 plots on the fly using par(mfg=vector) so switch between them. However, the appropriate scales aren't switched when changing from one plot to another, e.g. par(mfcol=c(2,1)) plot(1,1, col="blue") # blue plot plot(1.2,1.2, col="red") # red plot points(1.1,1.1) # appears to bottom left of red point par(mfg=c(1,1)) #

I have a dataset with 25 subjects and 25 items. For each subject-item combination, there's a 0/1 score for two parts, A and B. I'm thinking of this as a set of 2 x 2 tables, 25 x 25 of them. I'd like to fit a log-linear model to this data to test the independence of the A and B scores. If I ignore the subject and item parts, the following works just fine: glm(count ~ A * B,
