Swap values simultaneously. Present since hutils 1.4.0.
x %<->% value
| x, value | Objects whose values are to be reassigned by swapping. |
|---|
NULL invisibly. Called for its side-effect: the values
of x and value are swapped. So
x %<->% value
is equivalent to
temp <- x x <- value value <- temp rm(temp)
a <- 1 b <- 2 a %<->% b a#> [1] 2b#> [1] 1
