Hi.
Can anyone help me?
I want to create a vector from specific matrix-elements( e.g.[1,1]) these matrices are
elements of a list.
Is there any possibility to work without a loop? (e.g. with lapply?)
hope, you can help me
thank you
Michael

Sounds like you want
lapply(mlist, [, i = 1, j = 1)
where mlist is
Have you considere unlist? Also, note that a matrix is a vector with
a dim attribute, and a data.frame is actually a list with some other
attributes.
hope this helps.

hi Emkiba, try this:
x - matrix(1:12, 4, 3)
y - matrix(x, 12, 1)
yy - y[,1]
