[R] Coercion/conversion of logical index to integer index

[holki659@student.otago.ac.nz]

Hi all,

This question has significant potential to be a stupid one, but as I could find no hints in 
the manual or previous posts:

If you have a logical index X:

>X
[1] TRUE FALSE TRUE TRUE FALSE

And you want an equivalent integer index Y:

>Y
[1] 1 3 4

Is there no easy way?  (I'm thinking of the equivalent of FIND in Matlab)
