OK - this may be what you want:
> foo <- read.table('q.tbl', header=T, check.names=F, row.names=1)
> str(foo)
'data.frame': 5 obs. of 4 variables:
$ 30-Jan-08: num 1 2 3 4 5
$ 28-Feb-08: num 3 4 8 23 78
$ 31-Mar-08: num 7 4 655 4 6
$ 30-Apr-08: num 3 7 3 5 5
> foo
30-Jan-08 28-Feb-08 31-Mar-08 30-Apr-08
a 1 3 7 3
b 2 4 4 7
c 3 8 655 3
d 4 23 4 5
e 5 78 6 5
> foo['31-Mar-08']
31-Mar-08
a 7
b 4
c 655
d 4
e 6
> foo['d', '31-Mar-08']
[1] 4
Maybe row.names is not what you want - but the example sould get you going.
