simple coversion of matrix rows to matrix columns

Dear All

I would like to convert matrix rows to columns. I am thinking the t() function should help, but am having a hard time converting the matrix into the dimensions I would like them to. Example:

a <-matrix(c(1:30),ncol=3) gives me:[,1] [,2] [,3]
  [1,]    1   11   21
  [2,]    2   12   22
  [3,]    3   13   23
  [4,]    4   14   24
  [5,]    5   15   25
  [6,]    6   16   26
  [7,]    7   17   27
  [8,]    8   18   28
  [9,]    9   19   29
[10,]   10   20   30

I would like to convert the above into a matrix that looks like this with 3 rows and 10 columns:

1     2   3   4   5   6   7   8   9  10
11   12  13  14  15  16  17  18  19  20
21   22  23  24  25  26  27  28  29  30

I have tried :
b <-t(matrix(a))

but I am getting a 1X30 double matrix. I also Tried to specify
b <-t(matrix(a),byrow=TRUE,ncol=10)
but that does not help either...




apreciate your help,
