Possible memory leak with R v.2.5.0
I'm working with a very large matrix ( 22k rows x 2k cols) of RNA
expression data with R v.2.5.0 on a RedHat Enterprise machine, x86_64
architecture.
The relevant code is below, but I call a function that takes a cluster
of this data ( a list structure that contains a $rows elt which lists
the rows (genes ) in the cluster by ID, but not the actual data itself

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!

Memory leak with character arrays?
Hi -
When I'm trying to read in a text file into a labeled character array,
the memory stamp/footprint of R will exceed 4 gigs or more. I've seen
this behavior on Mac OS X, Linux for AMD_64 and X86_64., and the R
versions are 2.4, 2.4 and 2.2, respectively. So, it would seem that
this is platform and R version independant.
The file that I'm reading contains the upstream regions

How to remove/prevent trailing space after tab completion in R shell
Hi -
Not a mission critical issue, but still highly annoying. I just upgraded R
to 2.10.0 (the binary for Ubuntu karmic) and the tab completion facility now
inserts a space after every completed term (something it didn't do in 2.9.0
or 2.9.2). It wouldn't be an issue so much if it weren't for the fact that
it screws up tab-completing the next term, i.e. if I have a list of lists of

how can I attach a variable stored in
Hi -
Any help would be greatly appreciated.
I'm loading a list variable that's stored in an .RData file and would
like attach it.
I've used attach( <file_name> ), but that only lets me see the variable
that's stored in the file.
As the variable name is of the form "comp.x.x", I've tried using attach(
ls( pat="comp" ) ), but get an error as ls()

Suspected memory leak with R v.2.5.x and large matrices with dimnames set
Hi -
Admittedly, this may not be the most sophisticated memory profiling
performed, but when using unix's top command, I'm noticing a notable
memory leak when using R with a large matrix that has dimnames set.
To allow people to reproduce the problem I'm seeing, I've added a

[LLVMdev] Question about SmallVector implementation detail
Hello,
I have just a little question about the SmallVector implemention.
In SmallVectorImpl, the following method is currently implemented as:
void push_back(const T &Elt) {
if (this->EndX < this->CapacityX) {
Retry:
new (this->end()) T(Elt);
this->setEnd(this->end()+1);
return;
}
this->grow();
goto Retry;
}

__FILE__ object in R
Hi -
I'm curious if there is a way to get access to the location of the calling
script within R. I found one way of accessing it from this thread,
https://stat.ethz.ch/pipermail/r-devel/2008-April/048914.html, which
recommends using either:
parent.frame(2)$ofile
Or
FILE <- (function() {
attr(body(sys.function()), "srcfile")
})()$filename
However, those suggestions only

Code works standalone, yet same code fails when part of package
Hi
I'm missing something here but I cannot figure out what. What I can see is that the same code works when I load it via source(...) yet fails when I execute it after loading the package I have built (which includes the code.
Below is a transcript of my R session. First I load the code from a file, using source(). Then I execute it fine. Then I remove the function object, I load the

length of `...`
Hi,
It would be great if one of the experts could comment on the
difference between Hadley's dotlength and ...length? The fact
that someone bothered to implement a new primitive for that
when there seems to be a very simple and straightforward R-only
solution suggests that there might be some gotchas/pitfalls with
the R-only solution.
Thanks,
H.

length of `...`
The one difference I see, is the necessity to pass the dots to the function
dotlength :
dotlength <- function(...) nargs()
myfun <- function(..., someArg = 1){
n1 <- ...length()
n2 <- dotlength()
n3 <- dotlength(...)
return(c(n1, n2, n3))
}
myfun(stop("A"), stop("B"), someArg = stop("c"))

stopifnot
A private reply by Martin made me realize that I was wrong about
stopifnot(exprs=TRUE) .
It actually works fine. I apologize. What I tried and was failed was
stopifnot(exprs=T) .
Error in exprs[[1]] : object of type 'symbol' is not subsettable
The shortcut
assert <- function(exprs) stopifnot(exprs = exprs)
mentioned in "Warning" section of the documentation similarly fails
