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.

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))
