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)
