Dear R experts,
I am making a selectivity analysis using the package. Nevertheless, I am
having some troubles, and I would like to know if somebody know how to help
me:
1) When changing the x-axis labels. The programm uses the name habitat
instead of the names specified in the file.
2) Is it
I tried to run the sample code from R:

Dear all,I have a R structure that was created with replicate.The data sets
looks to be a matrix with each cell being a list.
str(error_suburban_0[,1],max.level=1)
List of 4

$ Shadowing:List of 2

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,
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)
pc.cr$scores[1:3, ]

I believe you are looking for 'text connections': see the 'text'
argument to read.table() and ?textConnection.
Thanks, that's it !

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
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!)

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

new features were added to both `melt` and `cast` for data.tables.
They both can handle multiple columns simultaneously. I think this
