The logical operators in R, namely &, | and !, are designed to work on logical vectors rather than bits. It is possible to convert from integer to logical vector and back to make these work as required, e.g.
<lang
logicalBitsToInt <- function(lb) as.integer(sum((2^(0:31))[lb]))
"%AND%" <- function(x, y)

bitOr(35, 42) # 43
