Source: R/assignFormals.R

...and assign them to objects with the same names in an environment (global is default). This is useful for testing and developing a function by running its source code line by line.

assignFormals(fun, envir = .GlobalEnv)

Arguments

fun

Function from which to extract defaults
envir

Environment in which to assign the default values of the arguments

Value

Nothing (invisible()). The function is only used for its side-effects.
