getBitIndicators: Operate on bit fields

In RCurl: General Network (HTTP/FTP/...) Client Interface for R

Operate on bit fields

Description

The getBitIndicators function decompose a value into its respective bit components. The setBitIndicators combines individual components into a single number to "set" a bit field value.

Usage

getBitIndicators(val, defs)
setBitIndicators(vals, defs)

Arguments

val	the value to break up into the bit field components.
defs	the named integer vector that defines the bit field elements.
vals	the individual components that are to be combined into a single integer value representing the collection of components. These can be given as names or integer values that correspond to the elements in the defs, either by name or value.

Value

getBitIndicators returns a named integer vector representing the components of the bit field in the value. The names of the vector give the symbolic elements that were set in the value.

setBitIndicators returns a single integer value representing the value from combining the different components (e.g. ORing the bits of the different values).
