Cast to list vector — as_vector.checkglobals • checkglobals

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

Usage

# S3 method for class 'checkglobals'
as_vector(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 list consisting of three character vectors:

global, vector of global function/variable names.
import, vector of import function/variable names.
package, vector of import package names.

Examples

## R-package from folder
chk <- checkglobals(
  pkg = system.file(
    "unit_tests", "pkg", "testpkg",
    package = "checkglobals"
  )
)
as_vector(chk)
