How can I neatly clean my R workspace while preserving certain objects?

Question

Suppose I\'m messing about with some data by binding vectors together, as I\'m wont to do on a lazy sunday afternoon.

    x <- rnorm(25, mean = 65, sd = 1         


        

Answer 1

Here is an approach using setdiff:

rm(list=setdiff(ls(), "dd"))
