At the risk of stating the obvious:

  - rm(.....)  # clears specific objects out of memory as soon as they're no
longer needed in the routine.

  - sapply(ls(), function(x) object.size(get(x)))  #lists all objects with
the memory each is using.

  - rm(list=ls())  #clears out all objects, e.g. before the routine, to free
up memory.
