[R-sig-teaching] Creating table from data.frame

[Byungchul Cha]

I am a relatively novice in R and I need some help. 

I want to create a two-way table from a data given as a data.frame, which looks like this:

> x
   group status gender count
1      1     s1     g1   890
2      2     s1     g2   969
3      3     s2     g1   340
4      4     s2     g2   403
5      5     s3     g1  2897
6      6     s3     g2  3321
7      7     s4     g1   249
8      8     s4     g2   383
9      9     s5     g1   306
10    10     s5     g2   366
11    11     s6     g1   160
12    12     s6     g2   137

I would like a two way table, which would look like

status    men    women
s1    890    969
s2    340    403
s3    2897    3321
...

How do I do this in a relatively efficient way? Thanks.
