Search for Masked Objects on the Search Path

Description:

     'conflicts' reports on objects that exist with the same name in
     two or more places on the 'search' path, usually because an object
     in the user's workspace or a package is masking a system object of
     the same name.  This helps discover unintentional masking.

Usage:

     conflicts(where = search(), detail = FALSE)

Arguments:

   where: A subset of the search path, by default the whole search
          path.

  detail: If 'TRUE', give the masked or masking functions for all
          members of the search path.

Value:

     If 'detail=FALSE', a character vector of masked objects. If
     'detail=TRUE', a list of character vectors giving the masked or
     masking objects in that member of the search path.  Empty vectors
     are omitted.

Examples:

     lm <- 1:3
     conflicts(, TRUE)
     ## gives something like
     # $.GlobalEnv
     # [1] "lm"
     #
     # $package:base
     # [1] "lm"

     ## Remove things from your "workspace" that mask others:
     remove(list = conflicts(detail=TRUE)$.GlobalEnv)
