Suggestion on how to make permanent changes to a single object in a list?
...have direct access to the objects' memory space. Onyway, one workaround would be to pass in the whole fooStack object and the index of the elt that you want to modify to the fooModifier fn, but I'd rather not have to pass the whole thing in. Any suggestions? Thanks! Peter Waltman

Running R under Sun Grid Engine with OpenMPI tight integration
Hi - I saw your posting on the R-help mailing list. Were you ever able to get this working? did you end up switching to use the rsge library? I'm trying to do the same, and not having very much luck getting it going. Thanks! Peter Waltman [[alternative HTML version deleted]]

Memory leak with character arrays?
...ed array and most likely aren't storing the text as ascii, but 4 gigs and up seems a bit excessive. Or is it? For an example, this is the output of top, at the point which R has processed around 5000 genes: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4969 waltman 18 0 *6746m 3.4g* 920 D 2.7 88.2 19:09.19 R Is this expected behavior? Can anyone recommend a less memory intensive way to store this data? The relevant code that reads in the file follows: ....code.... lines <- readLines( gzfile( seqs.fname ) )...

How to remove/prevent trailing space after tab completion in R shell
...ll result in a trailing space after the "$An.example" - "$An.example* *", requiring that it be deleted before the next term is specified. Any idea how to turn this off? Is this a shell integration issue? Something I'd need to do by compiling my own version? Thanks! Peter Waltman [[alternative HTML version deleted]]

how can I attach a variable stored in
.... I've also played around with eval(), but don't really quite get what that function does since it seems to get into the R internals which I don't entirely understand and I haven't found any great unified documentation on R's handling environment and scoping. Thanks, Peter Waltman

__FILE__ object in R
.... Because Galaxy places the executables within a user-specified directory, we can't hard-code that location if we want these to be general purpose, and would like access to that within the script, themselves, because in some cases, they need to be able to access each other.

how to generate pairwise plots with data frames - tia
...mes[1], test$myNames[2]) but that doesn't work either as the myNames members are strings, not the variables themselves (I believe). is it possible to get a listing of the variables themselve, not the names and work off of those? thanks to anyone who can help shed some light on this, Peter Waltman

Error with read.delim & read.csv
....2.5.1 on an x86_64, as well as v.2.6.0 on an x686 architecture. I also get similar behavior when I convert the file into a comma-separated file and use read.csv. As a quick workaround I can use scan & strsplit, but thought someone might want to take a look at this problem. Thanks, Peter Waltman p.s. the combination of scan & strsplit I describe above was as follows: my.lines <- scan( "trouble.txt", sep="\n", what='character' ) split.lines <- strsplit( my.lines, "\t" ) num.entries <- sapply( split.lines, length ) after whic...

Help with using 'get' function and variable scope
Hi - I'm having a really hard time w/understanding R's get function, and would appreciate any help with this. Specifically, I'm using a for loop to call a function. I'd like the function to have access to the variable being incremented in the for-loop, i.e. t.fn <- function() return( get( "i" ) ) t.fn2 <- function() { for ( i in 1:5 ) cat( t.fn(),

Looking for suggestions on how to debug pvm/snow proc's
Hi All - I'm running a faily long script that uses rpvm & snowFT to spawn off multiple processes with the 'clusterApplyFT' function. Specifically, what happens is that the head node generates a number of seed clusters that are then spawned off to the pvm cluster (in this case, nodes on a 4 dual-core machine) using clusterApplyFT to apply a function to each seed cluster that

Problem with loading RMySQL under sge/qsub
Hi - I'm trying to set up a parallelized batch job that is run under rmpi and managed by sge, using qsub, but it reports that it can't load RMySQL because it can't find the libmysqlclient.so.15 file. Note, when I run R interactively, and manually load the RMySQL library, it works without a hitch, however, when I have qsub launch R, it reports the following error: Error in
