[R] How do you delete variables from a data frame?

[Stuart Leask]

Is there a simple way of removing variables from a dataframe?

- rm(dataframe$VAR) doesn't seem to work
- Copying all but the unwanted variables into a new data frame is awkward
when there are a lot of variables.
- I haven't found any references to this in the help files.
