multithreading calling from the rpy Python package
...cussions on "why should we make R thread-safe
and how" on the website, but there appears to be no date on these
documents.
The R/Python wrapper functions I'm using:
# a variance calculator that returns 0 for vectors that have only 1
non-NaN element:
def vvar(a):
v=rpy.r.var(a, na_rm=True)
if isnan(v):
return 0
return v
# Calculate the Spearman Rho correlation between a and b and return the result
# as scipy.stats.stats.spearmanr() does:
R_spearmanr=rpy.r('function(a,b){ kk<-cor.test(a,b,method="spearman");
c( kk$estimate[[1]], kk$p.val...

Any interest in "merge" and "by" implementations specifically for sorted data?
Hi Developers,
I am looking for another new project to help me get more up to speed
on R and to learn something outside of R internals. One recent R
issue I have run into is finding a fast implementations of the
equivalent to the following SAS code:
/* MDPC is an integer sort key made from two integer columns */
MDPC = (MD * 100000) + PCO;
/* sort the dataset by the key */
PROC SORT;
