Hi all:
I have a problem when I want to do operation a sequence or matrix created by
loop and list() or data.frame(). Here is the example.
> for(i in 1:n) (k[i]=list(c(0:max[i])))
> k[1]+1
Error in k[1] + 1 : non-numeric argument to binary operator
What should I do to correct this problem?
Thanks
Peter
