Initializes the gxs_function() call with the arguments and default values of the selected function.

See `Details` for how to set a key command.

Usage

initializeGXSFunctionAddin(selection = NULL, insert = TRUE, indentation = 0)

Arguments

selection	Name of function to test with gxs_function(). (Character) N.B. Mainly intended for testing the addin programmatically.
insert	Whether to insert the code via rstudioapi::insertText() or return them. (Logical) N.B. Mainly intended for testing the addin programmatically.
