Simulation
Dear R users,
Can anyone please tell me how to generate a large number of samples in R, given certain distribution and size.
For example, if I want to generate 1000 samples of size n=100, with a N(0,1) distribution, how should I proceed?
(Since I dont want to do "rnorm(100,0,1)" in R for 1000 times)
Thanks for help

write.csv +RMySQL request
Hello,
I am relatively new to R and learning its ins and outs. As part of a website I am building, I need to read and write csv files directly from an SQL database. Basically I want to convert R variables (dataframes) into CSV format, store them as another R variable (as a properly formatted text string suitable for csv reading) and then send this to one row in a database.
The SQL part is fine,

Hi List,
I am experiencing an issue in a server that I have installed asterisk;
configured an AVM FRITZ card to work with the capi module.
Once istalled the card works perfect; however every time I reboot the

asterisk otherwise the capi module will not loadup.
Can anyone direct me in the right direction in order to

The specified network name is no longer available 3.0.25 RHEL4
I have a reproducible intermittent error large site - "The specified network name is no longer available".
This happens when copying large files. Below is part of log level 10 output & strace. Sorry for the long posting. I will probably need to put the loglevel 10 attached to a bugzilla - but thought I would try the lists initially.

Gamma
Hey,
I am having trouble graphing the following function
√2Γ(n/2)/[√n − 1Γ((n − 1)/2 for the values of n between 2 and 50.
i know that Γ(n) = (n-1)!, which in R is factorial(n-1)
When i type that into R, using y <- function(n).....
and
then plot(y,2,50), it doesnt give me anything meaningful, in fact, it
comes up with a message saying something like "in gamma(n+1) ploted" or

Xen/VirtualBox/Intel IOMMU HOWTO
Hi,
Treated myself to some new hardware as advance Eid/Diwali/Christmas/New
Year gift, and was trying to install Xen and get virtual machines
running on that. The path was long and arduous, and is still not
complete, but some of my experiences on the way are documented in:

dialplan issue - 1& 0 should be false
Helo List,
I'm having an issue using the AND (&) operator in the code of my dialplan.
The dial plan is coded to detect inbound DTMF digits from callers. key "1"
is equivalent to "yes" and key "2" is equivalent to "no" in my dial plan.
When a caller presses 1, yes is passed as a varialble and same when 2 is
pressed a "no" is passed.

General question about enabling partial inlining
Hi,
I noticed some performance gains in some spec benchmarks without
significant code size bloat when aggressively performing partial
inlining, especially when the original callee spill CSRs in the entry
block. I guess the partial inlining is not enabled mainly due to the
code size. Is there any other issue which prevent the pass from being
enabled? Do we have any plan or any on-going works

Misc patches
Hi,
Here are 3 suggested patches.
1. Build test for cmake and run the test in gitlab-ci.
2. Disable the message box on Windows on abort that cause test hangs in CI.
3. Build time improvement by removing unnecessary includes of stdio.h in production code and change to a lighter header intrin.h -> intrin0.h (windows only). Attached screenshot of measurement but it resulted in 14%

General question about enabling partial inlining
Hi Graham,
Thanks for sharing this. Are you planning on enabling the pass only on PGO?
Even in non-PGO, I noticed some performance gains when we are aggressive in
partially inlining the early return part, especially when the callee spill
CSRs in the entry block. At a high level, I have two questions:
1. What is the main obstacle that prevent the pass from being enabled
by default?
2.

[LLVMdev] Boostrap Failure -- Expected Differences?
The saga continues.
I've been tracking the interface changes and merging them with
the refactoring work I'm doing. I got as far as building stage3
of llvm-gcc but the object files from stage2 and stage3 differ:
warning: ./cc1-checksum.o differs
warning: ./cc1plus-checksum.o differs
(Are the above two ok?)
The list below is clearly bad. I think it's every object file in

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
