Empty-value selection operator

Return the left side unless it is NULL or has length zero, otherwise return the right side. Use %ss% when only NULL should fall through; that matches the rlang %||% operator without masking it.

Usage

a %|||% b

Arguments

a

The left side value to check.

b

The right side value to use if a is NULL or length zero.

Value

a if it is not NULL and has length greater than zero, otherwise b.

Examples

NULL %|||% 10
#> [1] 10
character(0) %|||% "fallback"
#> [1] "fallback"
5 %|||% 10
#> [1] 5
