Details

IsoplotR uses the following S3 classes to store geochronological data: UPb, PbPb, ThPb, KCa, UThHe, fissiontracks, detritals and PD, where the latter is the parent class of the simple parent-daughter chronometers RbSr, SmNd, LuHf and ReOs. All these classes have overloaded versions of the generic length() function and `[` subsetting method.
