Thanks.The code you gave me at the end works correctly.. I was wondering if
there is more efficient way to access each element withouth this classic for
loop.

I have an Arduino connected and I am trying to read from and write to a
serial connection using R. The problem involves the reading. I am able to
establish the connection using the following:

Before (I hope!) someone else answers in an unkind tone (and someone
probably will), I have a few suggestions:
1) please use plain text email (an option somewhere in your email

2) if at all possible, please try to const
Hello,

I am attempting to calculate MPD (mean pairwise distance), without weighting

Greetings, I am working on a project where we are applying the
Kruskal-Wallace test to some factor data to evaluate their correlation with
existing grade data. I know that the grade data is nonnormal therefore we
cannot rely on ANOVA or a similar parametric test. What I would like to
find is a me
David,
In data.table v1.9.5 (current development version, which you can get
from here: https://github.com/Rdatatable/data.table/wiki/Installation),
new features were added to both `melt` and `cast` for data.tables.
They both can handle multiple columns simultaneously. I think this
would be of inte
Dear anja,
You shouldn't really need XLConnect -- if it's absent, the only consequence
is that you won't be able to import Excel files directly in the Rcmdr. Just
say "no" when the Rcmdr asks to install XLConnect, and the Rcmdr GUI should
start up normally (unless there's some other problem). If
This is really a question about statistics rather than R but see below

Thanks for the quick response!
While I agree Rcommander is not the same thing as either ESS or RStudio, it
can also be useful as a wrapper when testing out functions and scripts. I
learned R on it and it's a more comfortable environment for me than ESS.
(Thank you for writing it!)
Strangely tcl
BTW I've also tried this as non-root:
R CMD javareconf -e
and there's still a problem with rJava not being able to access the library
that was supposedly compiled and installed in my home R directory.
I think it may have to do with the fact we're using an older version of R.
We're using Java 1.

Dear Angela,
There's very little to go on here. The messages to which you refer concern
primarily Mac OS X, where the most common problem is failure to install
XQuartz or to reinstall it after an OS upgrade. Help for this and other Mac
OS X problems is available in the Rcmdr installation notes, at
PCA 1, 2, and 3 refer to the scores not the loadings.
Check out the help for princomp.
?princomp
pc.cr <- princomp(USArrests, cor = TRUE)
