[LLVMdev] Crash in libunwind
Hello,
We have been investigating a crash in our application that may be related to how stack frames are generated by the JIT. We observe it with LLVM 2.9, but not with LLVM 2.8, everything else being the same. The crash occurs when dynamically generated code calls code that tries to unwind the stack.
Here is what the stack trace looks like on MacOSX 10.6 :
0 libSystem.B.dylib

[LLVMdev] Crash in libunwind
This may be bogus, but do you have:
llvm::JITExceptionHandling = true;
for the code that generates the dynamic code?
It has been a while, but I don't recall what will happen when dynamic code, generated
with jit exception handling turned off, invokes libraries which in turn try to unwind the stack
via the libunwind api. However given that you say the code works with 2.8, my concern

Error Bars in lattice- barcharts
Hello,
I am attempting to write a script that adds error bars to a barchart. I
basing my attempt heavily on the following thread:
http://tolstoy.newcastle.edu.au/R/e2/help/06/10/2791.html
I can't seem to get around the problem that was discussed in the thread. The
following example should illustrate my problem. Sorry about the messy
example but I am 1) trying to make it as close as possible

adding error bars to lattice plots
Dear R users,
About a year ago Deepayan offered a suggestion to incorporate error bars
into a dotplot using the singer data as an example
<<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/63875.html>>.
When I try to utilize this code with a grouping variable, I get an error
stating that the subscripts argument is missing. I have tried to insert
them in various ways, but cannot

How to show deug info via XENPRINTF?
Hi all.
I am trying to debug a kernel that I built, and I hope I could see some debug

"mod_start: 0x%lx mod_len: 0x%lx\n",

sequential treatment of a vector for formula
Please pardon the simplicity of this question of biological nature.
I'm trying to calculate a statistic, px, the proportion of a cohort
that survives through the interval x:x+1. I have the vector from
which the calc is to be made but I can't figure out how to tell R to
take the current value and divide it by the next value.
The formula is P0=L1/LO

interp.surface() error (PR#7745)
R version: 2.001
OS: Windows XP SP2
When I use the interp.surface() function, on occasion I have encountered
the following error message:
Error in interp.surface(a, loc) : subscript out of bounds
Since it is somewhat dependent on the data set, I cannot say exactly in
which cases these occur, but I believe I have found the problem and a
solution for it:

SCO Openserver Patch
I downloaded the Openssh-2.3.0p1 file and ran configure only to have it
fail reporting the lack of libz. I found that configure was failing
beacuse the test program did not include the libtinfo and libm which are
needed to resolve references in libprot. I made changes to the configure
script to add those libraries for SCO Openserver and then tried to compile
the programs only to run into another

does somebody use XCode on Mac for RoR instead of TextMate?
does somebody use XCode on Mac for RoR instead of TextMate? I wonder
how is it compared to TextMate... TextMate uses the default font of
Monaco... the Xcode screenshot on Wikipedia uses Courier... I wonder if
Xcode looks as good as TextMate when the font is changed to Monaco as
well? Thank you.

Accessing named elements of a vector
Dear R developers,
A great R feature is that elements of vectors, lists and dataframes can
have names:
vx = c(a=1, b=2)
lx = list(a=1, b=2)
Accessing element "a" of vx: vx['a']
Accessing element "a" of lx: lx[['a']] or lx$a
Might be a matter of taste, but I like the $ very much. Unfortunately,
vx$a is not
functional. Would it break existing compatibility
