Find missing values

Find missing (NA) values. This is smart enough to distinguish them from NaN values in numeric x. For all other types, it just calls is.na or anyNA.

anyMissing(x)

is.missing(x)

Arguments

x

Vector or array of atomic values.

Value

For anyMissing, a logical scalar indicating whether any NA values were present in x.

For is.missing, a logical vector or array of shape equal to x, indicating whether each value is NA.
