Suppose your data frame is called "mydat". Then something like
mydat[,sapply(mydat,class) %in% c('numeric','integer')]
might do what you want.

Hello,
I've got a data frame with a mix of numeric, integer and factor columns.
I'd like to pull out (or just operate only on) the numeric/integer columns.
Every thing I've found in searches is about how to subset by rows,
or how to operate assuming you have the column names.? I'd like to pull
by type.
Thanks!
Barry
