could not find function "%<>%"

Question

For some reason, R will recognize %>% (pipe operator) but not the %<>% (compound assignment pipe). The error I get is 'could not find function "%<>%"' - any ideas on how to fix this?

Answer 1

Load magrittr

library(magrittr)
x <- 4
x %<>% sqrt
x
## [1] 2

Note that overwriting variables can make debugging more difficult.
