Make a call with lazy_dots as arguments.

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.

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))
#> <lazy>
#>   expr: f(x = 1, 2)
#>   env:  <environment: 0x5636a3d4e5f0>
make_call(quote(f), list(x = 1, y = ~x))
#> <lazy>
#>   expr: f(x = 1, y = x)
#>   env:  <environment: base>
make_call(quote(f), ~x)
#> <lazy>
#>   expr: f(x)
#>   env:  <environment: 0x5636a3d4e5f0>

# If no known or no common environment, fails back to baseenv()
make_call(quote(f), quote(x))
#> <lazy>
#>   expr: f(x)
#>   env:  <environment: base>
