R help - May 2010 - create a data.frame for aov

Hi R-experts,

I try to find a way to transfer a matrix to a data.frame that is used as input
of aov.
can you give me advice for that?
>mdat <- matrix(c(1,2,3, 11,12,13), nrow = 2, ncol=3, byrow=TRUE, dimnames
= list(c("row1", "row2"), c("Col1",
"Col2", "Col3")))
>mdat
     Col1 Col2 Col3
row1    1    2    3
row2   11   12   13

===>
      row   col    dat
1    row1  col1  1
2    row1  col2  2
3    row1  col3  3
4    row2  col1  11

5    row2  col2  12

6    row2  col3  13
