[S] several questions

Sat, 3 Oct 1998 21:50:50 EDT

I'm not sure how to modify a data frame object so that I can delete columns of
data which are not necessary next to each other.

Suppose I have 6 columns - Y LY SY X1 X2 X3 X4 in a data set called SUSAN

where LY = log(Y)
and SY = sqrt(Y).

Suppose I have a function called stuff and I want to include Y and all the X
columns but exclude LY and SY.

>stuff(Susan[,-2:3], Susan[,1])

isn't working.
