It thinks twoSided is a variable, but you've never assigned such a variable.
Use "twoSided" instead - that's a string constant.

R respects LD_LIBRARY_PATH, see /usr/lib/R/etc/ldpaths where it
prepends its own path to any value in the environment when R is
invoked:
if test -z "${LD_LIBRARY_PATH}"; then
LD_LIBRARY_PATH="${R_LD_LIBRARY_PATH}"
else
LD_LIBRARY_PATH="${R_LD_LIBRARY_PATH}:${LD_LIBRARY_PATH}"
fi
export LD_LIBR

Yeah, R is difficult to search for - I've had partial success with
rseek.org, though.

Henrique,
I figured out what q[crossRsorted[,1]] does - it produces q[i] for all i in
crossRsorted[,1]. Ok. Since a given index 'k' of q[[k]] can oc

This appears to be doing something different. For instance, my 'q' has 165
components, but what you suggest has 15750:

This is just a guess: looks like you have GNU's Java version in your
path (aka "gcj").
Perhaps rJava relies on Sun's Java version.
If so, install Sun's Java first. apt-get install sun-java6-jdk might do it.

Thank you for the many replies! This is really a very friendly and

I think the above is what I was looking for since, presumably, it uses

Hi,
is there a simpler way to count the number of elements in a vector
that are not NA than this:
countN <- function (v) {
return (Reduce(function (x, y) x + y, ifelse(is.na(v), 0, 1)))
}
?

Hi,
I am confused about how to select elements from a list.
I'm trying to select all rows of a table 'crossRsorted' such that the
mean of a related vector is > 0. The related vector is accessible as
a list element l[[i]] where i is the row index.
I thought this would work:

Hi,
I am trying to use R for some survey analysis, and need to compute the
significance of some correlations. I read the man pages for cor and
cor.test, but I am confused about
- whether these functions are intended to work the same way
- about how these functions handle NA values
- whether cor.t
Hi,
I'm trying to make it easier for my survey evaluators to read the
results of my survey analysis. To that end, I'd like to suppress R's
habit of filling every line up to width columns. How do I do that?
For instance, using 'print()', R outputs something like:
[,1] [,
22 matches
