standardizeCall: Standardize call

In acidgenomics/r-acidbase: Acid Genomics Base Functions

Standardize call

Description

This function adds matching support for S4 methods with formals that aren't identical to the generic, and use a nested .local call.

Usage

standardizeCall(
  which = sys.parent(n = 1L),
  defaults = TRUE,
  expandDots = TRUE,
  return = c("call", "list"),
  verbose = getOption(x = "verbose", default = FALSE)
)

Arguments

which	the frame number if non-negative, the number of frames to go back if negative.
defaults	logical(1). Include default arguments in the call.
expandDots	logical(1). Should arguments matching ... in the call be included or left as a ... argument?
return	character(1). Return type. Uses match.arg() internally and defaults to the first argument in the character vector.
verbose	logical(1). Run the function with verbose output.

Value

• call: Matched call.

• list: Verbose list that includes additional information about how the call was standardized. Recommended for debugging purposes only.

Examples

aaa <- "AAA"
bbb <- "BBB"

## Standard function.
testing <- function(a, b) {
    standardizeCall()
}
testing(aaa, bbb)

## Inside S4 method.
setGeneric(
    name = "testing",
    def = function(a, ...) {
        standardGeneric("testing")
    }
)
setMethod(
    f = "testing",
    signature = signature(a = "character"),
    definition = function(a, b, ...) {
        standardizeCall()
    }
)
testing(aaa, bbb)
