any_na: Check whether there are any Missing Values in a Vector
Description
This function checks whether there are any missing values
in an R object. For list objects, we recurse over each
entry. This is typically faster than any(is.na(x))
as we exit and return TRUE
as soon as an NA
is discovered.
Usage
any_na(x, how = "unlist")
Arguments
how
The simplification to use if x
is a
list. See rapply
for more details.
