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.)
