Request for users of my R-Tcl/Tk examples, limmaGUI or affylmGUI
...the R stuff I've developed (and in how many countries). In particular I'm
talking about the R-Tcl/Tk examples I've put at
http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ and/or my two BioC
packages limmaGUI and affylmGUI (now maintained by Keith Satterley),
and/or the IBC2004 and JSM2005 microarray analysis course websites.
If it's not too much trouble, could you please tell me [OFF THE LIST] if
you use / have used any of these things (otherwise don't reply) and what
country you are from, and if there are many other people where you work
who use them but would not reply on...

Sampling with unequal probabilities
...rithms (though I don't recall if they used
the final random shuffle). Here's one description, or you
may prefer the description in

Comparison of Two Weighting Schemes for Sampling with Minimal Replacement
http://www.amstat.org/Sections/Srms/Proceedings/y2005/Files/JSM2005-000882.pdf
In the case of minimal = TRUE (sampling with minimal replacement),
with unequal probabilities:
* scale prob to sum to 1,
* randomly sort the observations along with prob
* let cprob = cumsum(prob),
* draw a systematic sample of size 'size' in (0,1):
uniformVector <- (1:siz...
