[R] Help translating S-Plus command

[Prof Brian Ripley]

It would help if we knew what that command was supposed to do.  My guess 
is that you want the Tr$size with the smallest value of Tr$dev, in which 
case

Tr$size[which.min(Tr$dev)]

would seem to do it.  However, there are details like what is to happen if 
there are ties for the smallest value.

(There are simpler ways in S-PLUS to sort one variable by the values of 
another, for example Tr$size[sort.list(Tr$dev)] which works the same way 
as in R.)
