Choose every second value
Instead of making two vectors, you might want to just have one matrix with two rows: amat <- matrix(a, nrow=2) Then you can do: amat[1,] amat[2,] Patrick Burns patrick at burns-stat.com +44 (0)20 8525 0696 http://www.burns-stat.com (home of "The R Inferno" and "A Guide for the Unwilling S User")

Dear list, is there a command that selects every second value from a given vector? For instance, a <- c(1,2,3,4,5,6) should yield 1,3,5 and 2,4,6 which i intend to place into two seperate vectors. best Alex
