[R] do.call([, ...) question

Hi again everyone I have an arbitrarily dimensional array a and a list jj of length length(dim(a)).The elements of jj are vectors of indexes. How do I use do.call() to extract a[ jj[[1]], jj[[2]], jj[[3]], ...] ? Toy example follows: a - matrix(1:30,5,6) jj - list(5:1,6:1) I want the following

This worked very well for me: do.call([, c(list(a), jj)) What about you? Kevin -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robin Hankin Sent: Wednesday, September 08, 2004 7:08 AM To: [EMAIL PROTECTED] Subject: [R] do.call([, ...) question Hi
