maxindex.default | R Documentation |
For is.booltype
objects the term length
is ambiguous.
For example the length of which
corresponds to the sum of logical
.
The generic maxindex
gives length(logical)
for all booltypes
.
The generic poslength
gives the number of positively selected elements, i.e. sum(logical)
for all booltypes
(and gives NA
if NAs
are present).
