R help - Jul 2009 - From "list" to "matrix"

Suppose, I have following 

vec <- vector("list", length=3)
for (i in 1:3) vec[[i]] <- matrix(rnorm((i+3)*2), (i+3))
vec


Now I want to change the type of "vec" from list to a matrix with
(4+5+6)
rows and 2 columns. How can I do that?

Thanks and regards,
