Re: [R] Using lapply with two lists

Hi Anna, Here is a suggestion: # creating L1 L1 <- lapply(1:5, function(x) matrix(rnorm(10), ncol = 2)) L1 # creating L2 L2 <- lapply(1:5, function(x) sample(5, 2)) L2 # defining a function foo <- function(x, y) list(x[-y,]) # result mapply(foo, L1, L2) HTH, Jorge On Fri, Mar 26, 2010 at 5:3
