Dear R users,
Usually the variance-inflation factor, which is based on R^2, is used as a
measure for multicollinearity. But, in contrast to OLS regression there is
no robust R^2 available for MM-regressions in R. Do you know if an
equivalent or an alternative nmeasure of multicollinearity is

Dear expeRts,
I collect some lab specific functions for a package.
Some of this functions need initial data
(ini files written in R-code). My question is:
Where is the place in the package structure for such files;
how to load the files?
I think something like:
I think was better for you to save data
with save(your.ini.RData) and use load(your.ini.RData)
to load it.
Best!

Please do read what writing R extensions says about the data directory.
This is not a correct use of that directory, and may well fail in the next
release.
I suggest you install them in an ini directory, by putting them in
inst/ini in the package sources.

Hi Laura,
Off the top of my head I'd suggest something like this (assuming your
data frames are named a and b)
a$ord - 1:nrow(a)
b$ord - (1:nrow(b))*2
c - rbind(a, b)
c - c[order(c$ord), ]
ie. add a new column that has the desired ordering, then join the two
data frames together, then reorder.
or something like
new.frame-rbind(x.frame,y.frame); # A frame of the right size.
new.frame[seq(1,nrow(x.frame),by=2),] - x.frame # Assign every other row
new.frame[seq(2,nrow(x.frame),by=2),] - y.frame # Assign every other row.

Yes, make a local installation on your home directory or another machine
which you have write access to.
AFAIK, you cannot update R itself. You will need to install R-1.9.1 and
delete the old version as opposed to upgrading from it. You can try to
salvage the lib directory but it is much better
