Problem with a if statement inside a function
I have a really long functions, and at the end of the function, I am using a
if statement
to tag certain keywords based on whether they have certain values contained
in them.
However, the if statement doesn't seem to work.
When I had split up the commands into various functions, it worked fine, but
I'm not sure
what going on now that it's combined into a single function.

strange strsplit gsub problem 0 is this a bug or a string length limitation?
I was working with the rmetrics portfolioBacktesting function and dug into
the code to try to find why my formula with 113 items, i.e. A1 thru A113,
was being truncated and I only get 85 items, not 113.
Is it due to a string length limitation in R or is it a bug in the strsplit
or gsub functions, or in my string?
I'd very much appreciate any suggestions

ENUM lookup issues with e164.org
Since e164.org added DNC and ADDRESS records my enum configuration has

Out of date instructions to build R using MKL
Hi!
I've been playing with MKL for a few days and I noticed the instructions
in the R Installation Administration manual [1] no longer apply. It
seems that since version 10.0 (the one used by the manual),
libmkl_lapack.so has been renamed/split (although the official
explanations seem to imply this was already the case in 10.0 [2]).
As a consequence, the instructions for dynamic linking no

Best Practices recommendation on x4200
Greetings all-
I have a new X4200 that I''m getting ready to deploy. It has four 146 GB SAS drives. I''d like to setup the box for maximum redundancy on the data stored on these drives. Unfortunately, it looks like ZFS boot/root aren''t really options at this time. The LSI Logic controller in this box only supports either a RAID0 array with all four disks, or a RAID 1

[PATCH v2 0/2] Implement VFP context switch for arm32
Hello,
This is the second version of this patch series.
I only implement the VPF context switch support for arm32 and add dummy function
to avoid compilation on arm64.
I have switched the order of the patch because the old second one can be applied
alone and the patch are cleaner :).
For all the changes see each patch.
Cheers,

population growth with the deSolve package. I would like to run the model
for four populations with the same initial population and carrying capacity
but with different growth rates and put the results into a data frame. When
I run the following lines of code I get unexpected results from "output" but

compler-rt, __aeabi_memcpy () possibly broken (ARM)
Hello,
I recognized that compiler-rt's the implementation of __aeabi_memcpy
simply branches to memcpy.
The implementation of memcpy is not provided. So an externally provided
memcpy () has to be used.
(also applies to memmove, memset, memclr)
On ARM I have seen implementations of memcpy () using floating-point
registers (if compiled with NEON support). The is perfectly
legal, as memcpy ()

Normal AAPCS functions are allowed to corrupt d0-d7 and d16-d31, but
the RTABI seems pretty explicit that these functions aren't. I think
we've got a real problem here.
