matchCall2

R Documentation

Remove `quote` and determine if call uses `...`

Description

Minor cleaning up of the FUN and ... to be used subsequently. This does only very minor things as it is run even if useCache = FALSE, i.e., even if the Cache is skipped.

Usage

matchCall2(definition, call, envir, envir2 = parent.frame(), FUN)

Arguments

`definition`	a function, by default the function from which `match.call` is called. See details.
`call`	an unevaluated call to the function specified by `definition`, as generated by `call`.
`envir`	an environment, from which the `...` in `call` are retrieved, if any.
`envir2`	Environment. The environment where `matchCall2` was called.
`FUN`	Either a function (e.g., `rnorm`), a function call (e.g., `rnorm(1)`), or an unevaluated function call (e.g., using `quote()`).

Value

A named list with call (the original call, without quote), FUNorig, the original value passed by user to FUN, and usesDots which is a logical indicating whether the ... are used.
