[R] Drop / Reshape

Hi all,
I have to reshape a dataset with many variables. Not all variables should be
included in the new dataset. Is it possible to NOT specify the drop-vector
of the reshape function explicitly? Instead I would like to drop all
variables that have not been used in one of the other arguments. If that is
possible, how could it be accomplished?
Thanks much,
Daniel

Betreff: Re: [R] Creating nice looking lists: how?
Others have shown you where to find the actual printing code for
print.summary.lm, but the short answer is:
Use the cat function for the general text (the word "coefficients:" and the
signif codes at the bottom) And put the actual coefficients in a matrix, use
colnames and rownames to add column and row headers, then use print.matrix
with quote=FALSE to print out the matrix of coefficients.
For more detailed printing look at ?cat, ?format, and ?sprintf.
Hope this helps,
