Hello
I am trying to store output from a loop into an empty matrix. The
current code I am using is:
M<-mat.or.vec(11,89)
R code to create a matix would use the matrix function,
for (j in list(3,91))
+ {M[,(j-2)]<-pic(datain[,j], mytree)}
You seem to be coming from a programming paradigm tha t uses "," where
R would use ":"
list(3,91) is a two element object rather than 3:91 which would be an
89 element object.
Perhaps you should read some introductory material and get a better
handle in the R syntax through self study.

datain is a matrix (11,91). I only want to use the pic() function on
the columns 3:91.
What pic function???
> ?pic
No documentation for 'pic' in specified packages and libraries:
you could try '??pic'
When I use this code output is stored into the 1st column of M and the
89th column of M but no other columns.
Any help would be greatly appreciated
