How to delete all "Values" in RStudio Environment?

Question

I know that rm(list=ls()) can delete all objects in the current environment.

However, environment has three categories: Data, Values, Functions. I wonder how I can only delete all the objects in one particular category? Something like

rm(list=ls(type="Values"))

Answer 1

You could use ls.str to specify a mode, or lsf.str for functions. The functions have print methods that make it look otherwise, but underneath are just vectors of object names, so

rm(list = lsf.str())

will remove all user-defined functions, and

rm(list = ls.str(mode = 'numeric'))

will remove all numeric vectors (including matrices). mode doesn't correspond exactly to class, though, so there's no way to distinguish between lists and data.frames with this method.

Answer 2

One option is that you can change the view to grid view and check all the boxes next to the ones you want to delete and click the broom button.
