How incredibly cunning. :-) Thanks for that.
Next stupid question. I've put together a simple coroutine/fibre style
threading system on top of the Linux setcontext/getcontext stuff, which
surprisingly enough seems to work *almost*

Is it possible? If so, can you explain to a newbie (me) precisely how it is done?

Pfilestat vs. prstat
[Just starting out with DTrace and was hoping to get some guidance.]
I have a "benchmark" program that I monitored with both prstat (prstat -mL -P <PID>) and pfilestat (from the DTrace toolkit). Prstat reports LAT values in the 0.1-0.2% range, but pfilestat reports "waitcpu" values in the 6-10%. Since those two numbers supposedly represent time waiting for the CPU,

About memory index/search in multithread program
hi,
Why xapian don't support memory index/search ?
I know there is a method can create memory datebase, like this:
Xapian::WritableDatabase db(Xapian::InMemory::open());
*But, if i use these in multithread program, i need create many
datebases!!*
Xapian::WritableDatabase db1(Xapian::InMemory::open()); //used in thread1

Re: [BioC] limma, FDR, and p.adjust
Mark,
there is a fdr website link via Yoav Benjamini's homepage which is: http://www.math.tau.ac.il/%7Eroee/index.htm
On it you can download an S-Plus function (under the downloads link) which calculates the false discovery rate threshold alpha level using stepup, stepdown, dependence methods etc.
Some changes are required to the plotting code when porting it to R. I removed the

Changing parameter in local fdr R code
I am using Efron's local fdr procedure. But, I want to change the null from
N(0,1) to N(0, 0.002). I can access the function but I have no idea what to
change. In other words, I want nulltype to be N(0,0.002) instead of N(0,1)
in his function. Anyone has any ideas. This is his code for the local fdr:
function (zz, bre = 120, df = 7, pct = 0, pct0 = 1/4, nulltype = 1,
type = 0, plot = 1,

limma, FDR, and p.adjust

[BioC] limma, FDR, and p.adjust
You asked the same question on the Bioconductor mailing list back in August. At that time, you
suggested yourself a solution for how the adjusted p-values should be interpreted. I answered
your query and told you that your interpretation was correct. So I'm not sure what more can be
said, except that you should read the article Wright (1992), which is cited in the help entry for
p.adjust(),

topTable function from LIMMA
Dear R-Help,
I am using the function "topTable" from the LIMMA package. To estimate
adjusted P-values there are several options (adjust="fdr" , adjust="BH")
as shown below:
topTable(fit, number = 10, adjust = "BH", fit$Name)
I guess any of these options (fdr, BH, etc.) is using a default of
FDR=0.05 which is quite conservative (i.e., very

Redirect standard input and output of R
Dear R-people!
I??m trying to write a C program that write to the standard input of R
and read the standard output.
I can perfectly read the R output, but I??m not able of writing anything
to R.
This program really works with the 'cat?? UNIX command, but it does not
work with R. What I??m doing wrong??? It is possible to do it???
I want to start R once and use it thousands of times...

building llvm_Rel400 on Scientific Linux (RHEL) 7.3 x86_64
Hi,
I am trying to build the LLVM suite on a RedHat Enterprise Linux clone (Scientific Linux <https://www.scientificlinux.org/>). In the latest attempt, the build seems to complete without any explicit failures but the `check-all` process fails. Any ideas about what is wrong or suggestions for how to proceed would be much appreciated.
