R: Make a call with 'lazy_dots' as arguments.

make_call {lazyeval} | R Documentation

## Make a call with `lazy_dots` as arguments.

### Description

In order to exactly replay the original call, the environment must be the same for all of the dots. This function circumvents that a little, falling back to the `baseenv()` if all environments aren't the same.

### Usage

    make_call(fun, args)

### Arguments

`fun` | Function as symbol or quoted call.
`args` | Arguments to function; must be a `lazy_dots` object, or something `as.lazy_dots()` can coerce..

### Value

A list:

`env` | The common environment for all elements
`expr` | The expression

### Examples

    make_call(quote(f), lazy_dots(x = 1, 2))
    make_call(quote(f), list(x = 1, y = ~x))
    make_call(quote(f), ~x)

    # If no known or no common environment, fails back to baseenv()
    make_call(quote(f), quote(x))
