na()
: Logically indexes NA
values of x
. Returns a logical object of the same dimension as x
.
ok()
: Logically indexes non-NA
values of x
. Returns a logical object of the same dimension as x
.
sub_na()
: Substitutes sub
for NA
values ofx
. Modes of x
and sub
must be compatible. Returns x
with NA
values replaced.
na0()
: Evaluates whether x
is an atomic NA
scalar. Returns a logical scalar.
ok0()
: Evaluates whether x
is an atomic, non-NA
scalar. Returns a logical scalar.
rm_na()
: Removes NA
values of x
If there are no NA
values in x
, returns x
unchanged. If there are NA
values in x
, removing them may change the dimensions and/or class of x
. Returns x
with NA
values removed.
