The R package masscor provides functions, classes and
methods to support mass measurements using digital balances. The
provided classes can store the calibration information for balances and
mass standards, to later allow the conversion of balance readings to
both conventional mass and real mass, and to perform routine balance
verification by using the normalized error function. Air buoyancy
correction factors are calculated using local air density that can be
calculated using measured environmental conditions and applying one of
several models available in the package. The uncertainty of (corrected)
mass measurements can also be calculated allowing to further asses the
suitability of a given mass measurement.
