Removing NULL objects from an environment

Question

I have an environment of objects that are either xts or NULL. I would like to remove all the NULL from the environment. Is there a function I can use with eapply to achieve this?

Answer 1

rm(
  list=names(
    which(
      sapply(globalenv(),is.null) # or .GlobalEnv
      )
    )
  )

If it's not the global environment, you can use the envir switch in rm and wrap the environment name in getenv() in the sapply call
