Hi:
It's just an extra step:
y <- list(list(c(1,5),c(2,3,4)), list(c(1, 3, 4), c(5, 7)))
lapply(seq_len(length(y)), function(i) lapply(y[[i]], min))
[[1]]
[[1]][[1]]
[1] 1
[[1]][[2]]
[1] 2
[[2]]
[[2]][[1]]
[1] 1
[[2]][[2]]
[1] 5
unlist(lapply(seq_len(length(y)), function(i) lapply(y[[i]], min)))
[1] 1 2 1 5
HTH,
Dennis
