Hi there. I went through the manual but I couldn't find a solution for my problem. I have list like this one :> lst1[[1]] [1] 0 1 2 3 [[2]] [1] 0 1 5 [[3]] [1] 2 3 4 and I want to save it as Matrix in Matlab mat format like : 0 1 2 3 0 1 5 0 2 3 4 0 can any body help me ? Appreciate your help and thanks in advance.

Try this: t(sapply(lst1, '[', 1:max(sapply(lst1, length)))) On Sat, Sep 3, 2011 at 3:37 PM, wizykid <wizy.kid at gmail.com> wrote:> Hi there. > > I went through the manual but I couldn't find a solution for my problem. > > I have list like this one : >> lst1 > [[1]] > [1] 0 1 2 3 > > [[2]] > [1] 0 1 5 > > [[3]] > [1] 2 3 4 > > and I want to save it as Matrix in Matlab mat format like : > 0 1 2 3 > 0 1 5 0 > 2 3 4 0 > > > can any body help me ?
