Hi,
It might be a trivial question but how do you store matrices of different dimensions read from a file or in a loop together? The best solution might be a list but I don't store the first matrix  correctly:

 m = rbind(c(1,2),c(3,4),c(5,6))
t=rbind(c(1,2),c(5,6))


 l = list(m)
> l = list(l,t)    #I assumed that at the begining I don't have m and t at the same time to do list(m,t), but I list them, one after the other
> l
[[1]]
[[1]][[1]]
     [,1] [,2]
[1,]    1    2
[2,]    3    4
[3,]    5    6


[[2]]
  [,1] [,2]
t    1    2
     5    6


thanks

Carol
