Find the proportion of values of `x`

that are `%out%`

of the vector `y`

.

`prop_out(x, y, na.rm = TRUE, ignore.case = FALSE)`

## Arguments

- x
A vector to check.

- y
A vector to compare against.

- na.rm
logical; Should `NA`

be ignored?

- ignore.case
logical; if `FALSE`

, the pattern matching is case
sensitive and if `TRUE`

, case is ignored during matching.

## Value

The proportion of `x`

absent in `y`

.
