Specify missing values for a vector

Change specified values to NA

specify_missing(x, ..., default_missing = c("", NA, "blanks"))

`x`	vector
`...`	values that should be changed to `NA` if found in `x`
`default_missing`	a vector with additional default values to change to NA. These are treated the same as `...` but are added by default if not removed. A special value `"blank"` can be used to indicate all empty strings (all characters matching `[:blank:]`, see regex).

x itself but with specified values set to NA.

x <- sample(100)
x[sample(100, 10)] <- 999
specify_missing(x, 999)
