[LLVMdev] Possible memory leak in LLVM 2.5
Hi Reid,
I guess it's not so much a memory leak, as unexpected behaviour, resulting in excessive memory use.
I also call the following after EE->runFunction, which seems to clean up pretty nicely.
EE->freeMachineCodeForFunction(stub);
// Delete functions and IR.
stub->deleteBody();
stub->eraseFromParent();
Rob.

Problem with updating/reinstalling R under UBUNTU (Hardy)
Hello,
I am a new R user not at ease with installing and updating R package under Ubuntu (Hardy), so that I cannot run R anymore ...! I initially installed r version 2.6.2.2 (amd64) from Intrepid instead of Hardy (!), but it worked. I tried to update to version 2.9, but did not succeeded:

[LLVMdev] Possible memory leak in LLVM 2.5
I'm unfamiliar with the leak you've just described, but Jeffrey
Yasskin has done a lot of work cleaning up leaks for 2.7 and trunk.
I was just going to mention that unless the function you are calling
via runFunction has a simple prototype that's special cased in
runFunction, it will generate its own stub function for every call.
If you don't want to worry about that, you can call

What determines the order of rows in a lattice barchart?
Hi,
What determines the order of the rows in a barchart?
Cheers,
Geoff.
Here is my code, and the data follows. If I have z in alpha order, the
barchart is in
some order I can't determine. I originally tried
rownames(twater)~twater$Cat, but the
chart wasn't in rownames(twater) order either.
library(lattice)
twater<-read.csv("totalwater.csv",strip.white=T)

function in R that's equivalent to SQL's "IN"
Hi all,
I'm trying to find
something like the "==" operator that will work on vectors or something
equivalent to SQL's "IN" function. For e.g., if I have:
x <- c(1,2,3,4,5)
y <- c("apples", "oranges", "grapes", "bananas", "pears")
z <- data.frame (x,y)
w <- c(2,4,5)
I want R to return the values

[LLVMdev] Possible change to ExecutionEngine::create()
Hi Rob,
Can you comment on exactly what the problem is you want to solve? Is
it a performance issue with LoadLibraryPermanently, or do you simply
not want the external symbols to be resolved from within the JIT?

[LLVMdev] Possible change to ExecutionEngine::create()
Hi Daniel,
In my case ExecutionEngine::create() loads 40 modules, then each time I try to resolve a symbol that I know is in a DLL that I supply, it looks through all 40 modules first. This is on Windows, so I get the following modules loaded:
ntdll.dll, kernel32.dll, USER32.dll, GDI32.dll, SHELL32.dll, ADVAPI32.dll, RPCRT4.dll,
Secur32.dll, msvcrt.dll, SHLWAPI.dll, ole32.dll, OLEAUT32.dll,

Add col in data.frame
Hello Gurus,
I am still new to R. Here is my issue.
I was trying to add column to data frame that was populated by read.spss().
When I used cbind to add a new variable(column).
library(foreign)
mydf<-read.spss(file="C:/myspss.sav",use.value.labels=FALSE,
to.data.frame=TRUE,use.missings=FALSE)
attr(mydf,"variable.labels")
## it gives you all the labels

more Matrix weirdness
I think that this is because `[<-` dispatches on S4 methods only if the first argument is S4.
?"[<-" says:
"These operators are also implicit S4 generics, but as primitives,
S4 methods will be dispatched only on S4 objects ?x?."

[LLVMdev] Possible memory leak in LLVM 2.5
Hi,
I'm current using LLVM 2.5 to JIT code in a event driven language running on a game engine. Haven't updated to 2.7 yet, but I do intend to.
When checking for memory leaks I found that each time I was calling EE->runFunction after creating a stub function to execute an event, all the pass information was being repeatedly added to PMDataManager.
I have changed addAnalysisImplsPair

Question about --files-from= and folder structure
I'm writing a script to sync some mp3 files. Due to a limitation in the
number of destination files that can be read from my thumb drive, I'm
not looking to preserve the original file structure (actually, I'm
looking to sync *only the files* to the new destination directory).
The source files are all subfolders under /backup/Music:

Speed-up/Cache loadNamespace()
Thanks for the quick responses. As you both suggested storing the packages
to local drive is feasible but comes with a size restriction I wanted to
avoid. I'll keep this in mind as plan B.
@Hugh: 2. would impose even greater slowdowns and 4. is just not feasible.
However, 3. sounds interesting - how would this work in a Linux environment?
Thank you,
Mario

readLines interaction with gsub different in R-dev

No, I don't think R-devel is correct (or at least consistent with the

Proposed speedup of ifelse
I propose a patch to ifelse that leverages anyNA(test) to achieve an
improvement in performance. For a test vector of length 10, the change
nearly halves the time taken and for a test of length 1 million, there
is a tenfold increase in speed. Even for small vectors, the
distributions of timings between the old and the proposed ifelse do
not intersect.
The patch does not intend to change the
