try this:
mat <- matrix(unlist(lis), ncol=2, byrow=TRUE)
I hope it helps.
Best, Dimitris

Subject: [R] How to convert a list to a matrix
Hi
Sorry to ask such a basic question. I have a list, each element of
which is a vector of two values. What I actually want is a matrix with
two columns, and one row per element of the list. Obviously I have
tried as.matrix(), and as.vector() but I didn't expect the latter to
work.
I feel so lame asking this. Any suggestions?
Mick
