[R] data.frame subsetting

[Douglas Bates]

Still works for me in both 1.7.1 and 1.8.0 (in development)

> data(women)
> women[["height"]]
 [1] 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72
> women$height
 [1] 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72

Can you provide an example of how it is failing for you?
