bitcheck: Function evaluating the flags bit

In rfxf/Rfdbk: Handling NetCDF feedback files

Description

Some feedback file attributes are integers that have to be transformed to a bit string in order to encode the feedback file report (e,g, flags or level_sig). This function takes the integers as input and a vector of bits and returns TRUE/FALSE if bit is part of the bit-converted integer The first bit is 0 (not 1), in agreement with the construction of feedback files.

Usage

bitcheck(int, bits)

Arguments

int	a integer or a vector of integers that is converted to bits
bits	a bit or a vector of bits that might be contained in each int

Value

logical if bit is in the converted integer
