invoke | R Documentation |
These functions were superded in purrr 0.3.0 and deprecated in purrr 1.0.0.
invoke()
is deprecated in favour of the simpler exec()
function
reexported from rlang. exec()
evaluates a function call built
from its inputs and supports dynamic dots:
# Before: invoke(mean, list(na.rm = TRUE), x = 1:10) # After exec(mean, 1:10, !!!list(na.rm = TRUE))
invoke_map()
is deprecated because it's harder to understand than the
corresponding code using map()
/map2()
and exec()
:
# Before: invoke_map(fns, list(args)) invoke_map(fns, list(args1, args2)) # After: map(fns, exec, !!!args) map2(fns, list(args1, args2), \(fn, args) exec(fn, !!!args))
