Hello,
I am trying to find a function name in a string that expresses a
functional form :
s = blabla...S(var)...blabla
I would like to detect the pattern S(*) in s.
I am no guru at regular expressions. Just tried :
grep(S(.*),c(S(a),CSP))
[1] 1 2
I expected the pattern to be retrieved
Jonathan,
If you are not willing to use the very last version of R, there is
always a RPM package for R under Mandriva, called R-base. So that
basically, connected as root, just type:
urpmi R-base
to install it.

Dear R users,
I'm trying to have a gWiddgetsRGtk2 script run under R-2.4.1. The script
run OK under Linux but all accentuated characters appear as ? when the
script is run under Windows.
As Gtk+ requires UTF-8, I thought it was the source of the problem and
tried to change the default
Hello,
I noticed the following strange behavior under R-2.4.0 (Linux Mandriva

Rafael,
when testing binomial hypotheses with both repeated measures and
inter-group factors, you should make explicit your model on the
intra-subject part of the data. You can't do Chi-square comparisons on
count data that mix independent and dependent measures.
But you can define a
has anyone written a package/function in R for computing a point-
biserial resp. biserial correlation?
Note that the point-biserial correlation is nothing but the standard
correlation coefficient when one of the variables is dichotomous, so that
cor(.) is OK.
The biserial is different and
