Cast to character

Source: R/as.R
as.character.checkglobals.Rd

Cast an S3-object of class "checkglobals" to a character vector.

Usage

# S3 method for checkglobals
as.character(x, pattern, which = c("global", "import"), ...)

Arguments

x

object inheriting from class "checkglobals".

pattern

an optional regular expression. Only names matching pattern are returned. glob2rx can be used to convert wildcard patterns to regular expressions.

which

a character vector, either "global" to print all unrecognized global variables, "import" to print all detected imported functions and variables, or both (default).

...

additional arguments to configure the output:

  • all.names, a logical value. If TRUE, all object names are returned. If FALSE, names which begin with a . are omitted. Defaults to TRUE.

  • sorted, a logical value indicating if the function/variable names should be sorted alphabetically. Defaults to TRUE.

Value

a character vector containing the names of the global or imported function/variables.
