Hi,
I have been suggested to use Information theoretic approach instead of a
Geneal linear model for a multiple regression. Is is possible to perform
this type of anlaysis in R?
Thanks,
Adela

Hi all,
Does anyone know where to find more information on the by class?
OR
Does anyone know how to coerce an object of the by class into a
data.frame containing the results of FUN and the values of the
grouping variables?
Dear R-experts,
I imported successful a workspace from Matlab. The information is stored
in the variable data. If I use the command length(data) I get back a
number which corresponds to the number of variables which were imported.
Here it is 82. Now I only want to know the names of the imported

thank you. It is exact what I wanted. Now I can modify my program.

sna uses adjacency matrices, so one (crude) solution would be to store the

It's not clear to me what you want; the on-line help states that
approxfun() does linear or constant interpolation (the default is
linear). It is trivial to write down a ``mathematical
representation'' of the resulting function --- but why would you want
to? The function f() you created does

I don't know about profyle analyses, but have a look at the packages
nlme (or lme4) which can do
repeated measures.
