key-value mapping in C inside R?
I'm testing some modifications in arima.c.
I've noticed that a big internal array of double (rbar) is usually
sparse and I'd like to add an option to store it as key-value mapping.
Is there a library function or some other approach already used inside
the R core for key-value mappings?
Thanks,

cronbachs alpha - score.items(psych) vs reliability(Rcmdr)
Dear all,
I like the way the Rcmdr package computes reliability. E.g
reliability(cov(d[,c("q1", "q2", "q3", "q4", "q5", "q6")],
use="complete.obs"))
will not only give me the alpha score, but also for each variable,
alpha.score if deleted. However - when writing scripts it's very tiresome to
load the whole Rcmdr GUI just

arima() bug
I guess this is more r-devel than r-help.
Note, I am just the messenger - I have no idea what the user is trying to model here.
arima() crashes R (segfault) with Linux R-2.7.0, Solaris R-2.6.0:

CircStats Bug? (PR#11266)
...irc.summary and circ.disp
seems to conclude that the dimension is 1.
I am new to R so maybe I'm just missing something.

Meta-Analyisis on Correlations
Dear R-Community,
I'm currently trying to find a way to conduct a meta-analysis in R.
I would like to analyze data from mostly-cross-sectional survey-studies. The
effect sizes would be correlations.
The R packages "meta" and "rmeta" are, as far as I can see, set up for
analysis with effect sizes for differences (i.e. comparison of the
means/odds-ratios of experimental
