Dear Friends.
I am just starting to use R. And in this occasion I want to construct a
high-dimensional contingency table, because I want to crate a mosaic plot
with the vcd package.
My table is in this format:

    año ac.rep    cat.gru conteos
1  2005      R    parejas     253
2  2005      N    parejas      23
3  2006      R    parejas     347
4  2006      N    parejas      39
5  2007      R    parejas     266
6  2007      N    parejas      83
7  2005      R solitarios      53
8  2005      N solitarios       1
9  2006      R solitarios     109
10 2006      N solitarios       8
11 2007      R solitarios      85
12 2007      N solitarios      34
13 2005      R      trios      29
14 2005      N      trios       1
15 2006      R      trios      62
16 2006      N      trios      19
17 2007      R      trios      48
18 2007      N      trios       3

How can I do this?
I saw the help of the "mosaic" command, and I found that the files are like
a hig-dimensional contingency table (for example "Tytanic" data), but I was
unable to do the change.
Thank you very much!!!
With best wishes
