R: Default value for 'NULL'

op-null-default {rlang}

R Documentation

Default value for `NULL`

This infix function makes it easy to replace NULLs with a default value. It's inspired by the way that Ruby's or operation (||) works.

x %||% y

x, y

If x is NULL, will return y; otherwise returns x.

1 %||% 2
NULL %||% 2
