prevent conversion to factors in aggregate?
I've been trying to figure out how to prevent a column that is the result of
an aggregate function call so that I can use it in further calculations. For
example, I would like to aggregate the expf for the data.frame by sp
(character) and dbh (double d=rounded to integer) using the command:
> st2 <- aggregate( ntrs$expf, by=list(sp=ntrs$sp,dbh=ntrs$dbh), sum )
> st2$expf <- st2$x

mapping calls to exp() to expf opcode
We've got both an sqrtf and an expf opcode in our architecture. If I call
sqrt() on the C side, I see the sqrtf opcode show up in the generated
assembly. However, if I call exp() on the C side, I don't see the expf
opcode show up on the generated assembly, I see a call to an exp function
from libm.
Here's what we've got in our TargetInstrinfo.td file for both of these

aggregate question...
R-folks,
Is there a function, like aggregate, that allows users to bin values?
I've got to break down a data frame into classes of 5cm (or something like
it), and I only know how to do it using code like,
signif <- symnum( stems$dbh,
corr = FALSE,
na = FALSE,
cutpoints = c(0,10,20,30,40,999),
symbols = c(0,10,20,30,40) )

[LLVMdev] getTripCount and pointers
Hello,
I'm having some trouble with getTripCount() ... again. In particular
it fails in the first of the following two examples, although it works
for the second. By fails, I mean it returns NULL.
---------- example 1 ----------
test1(int *a, const int *ip) {
int k;
for (k = 0; k < ip[2]; ++k) {
a[k] = (k+11)/(k+2);
}
}

Targeting old glibc
Hi,
I wonder what is the right way to target an old glibc?
I have a machine which is up to date (glibc 2.32 and clang+lld 10.0.1).
So far I've been able to target older glibc by having a C file containing:
__asm__(".symver powf,powf at GLIBC_2.2.5");
__asm__(".symver expf,expf at GLIBC_2.2.5");
__asm__(".symver exp2f,exp2f at GLIBC_2.2.5");

R function for Probabilities for the (standard) normal distribution
Dear All,
I need to write an R function which computes values of Probabilities for
the (standard) normal distribution, ¦µ(z) for z > 0 by summing this power
series. (We should accumulate terms until the sum doesn't change). I also
need to make the function work for vector of values z.
The initial fomular is
¦µ(z) = ( 1/ sqrt(2¦Ð) )* ¡Ò e^(-t^2/2)dt (¡Ò is from -¡Þ, z)

VGA passthrough nVidia NVS 295
I want to try to get VGA passthrough working in a Windows 7 x64 domU.
I''m running debian squeeze/testing/unstable with Jeremy''s 2.6.32.x kernel.
The best I got to work is the device showing up under Windows 7, with

[PATCH] xen: arm: Fixing ttbcr (TCR_EL1 for AArch64) size.
This patch fixes size of ttbcr register (TCR_EL1 in case of AArch64)
and it''s programming considering size in case of context switch.
Currently ttbcr is defined as 32b register but for AArch64 TCR_EL1
size is 64b.

data is getting corrupted
I've been attempting to perform some analysis on a model that was
interfaced with R (R calls a library that takes SEXPs and converts the
data frames into the internal structures of data), and I notice that for
small data.frames the vectors don't get corrupt (n<200-ish). When I pass
in larger data.frames, the vectors will become corrupt. I've been

-ffast-math optimizations impacted by symbol renaming in header files
Hi,
I came across an issue where some optimizations that would normally be applied to standard math function calls are not getting applied when the –ffast-math option is enabled on the Clang command line on a Linux x86_64 target.
I tracked down the issue to occurring because the –ffast-math option is triggering Clang to preprocess the math.h header file with the __FINITE_MATH_ONLY__ macro set

nlme and spatially correlated errors
Dear R users,
I am using lme and nlme to account for spatially correlated errors as
random effects. My basic question is about being able to correct F, p, R2
and parameters of models that do not take into account the nature of such
errors using gls, glm or nlm and replace them for new F, p, R2 and
parameters using lme and nlme as random effects.
