Arguments

x

an object of classes bit, bitwhich, ri or something on which which works

maxindex

the length of the boolean vector which is represented

...

further arguments (passed to which for the default method, ignored otherwise)

is.unsorted

a logical scalar indicating whether the data may be unsorted

has.dup

a logical scalar indicating whether the data may have duplicates

range

a ri or an integer vector of length==2 giving a range restriction for chunked processing

Details

as.which.bit returns a vector of subscripts with class 'which'

Value

a vector of class 'logical' or 'integer'
