rm(list=ls()) doesn't completely clear the workspace

Question

This is a very minor issue, but I would like to understand exactly what is going on here.

Say I do the following:

library(RMySQL)
con <- dbConnect         


        

Answer 1

R itself says, in the help for rm:

## remove (almost) everything in the working environment.
## You will get no warning, so don't do this unless you are really sure.
rm(list = ls())

Note the 'almost'. There are different environments.

Did you try detach(values1)?
