[R] rbind question

Hi I am trying to replicate a vector in n rows for comparison purposes with another matrix. foo - c(1,2,3) bar - rbind(foo,foo) # does the trick for 2 rows bar - rbind(rep(foo,2)) # does something else How do I generate a matrix with all rows=foo without writing 'foo' n times as arg? Thanks,

What about: matrix(rep(foo,2),ncol=length(foo),byrow=TRUE) -Original Message- From: David Andel [mailto:[EMAIL PROTECTED] Sent: 08 July 2003 14:58 To: [EMAIL PROTECTED] Subject: [R] rbind question Hi I am trying to replicate a vector in n rows for comparison purposes
