How can I change the library path in R? I don't have permission to write to
the default R library on the computer I am running R on.
I have searched the forum and have not found anything that I understand, so
I apologize if this has been asked before.
Thanks very much!

the current code is like this
vidx<-grep(paste('^',vars[vi],'$',sep=''),gsub("[[:punct:]]","",strrl1[[datbeg-1]]),ignore.case=T)
where as the old one was
vidx<-grep(vars[vi],gsub("[[:punct:]]","",strrl1[[datbeg-1]]),ignore.case=T)

If I understand correctly you want to create a new dataframe with selected
columns which can be achieved this was as well, it will right away create a
new dataframe with column headers
df2<-df1[ ,c(3,7,9,11,13,15)]

proposed by Higham (1988).
However, when I deal with correlation matrices whose diagonals have to be 1 by
definition, how do I do it? The abov
Hi,
Is it possible to include factor variables as model inputs using this
package? I'm quite sure it is not possible, but would like to double check.
Thanks,
