Common lead isotopic data can provide important information on the history and the evolution of geological samples. Evaluation of common lead datasets need specific calculations e.g. iterative Pb207/Pb206 age calculation, linear regression with correlated errors and sometimes principal component analysis (PCA). These calculations can be performed by modern computers, but a set of pre-defined functions would be helpful, as these calculations are not always trivial.This paper presents an implementation of some basic functions for Octave, a GNU public license program, for the evaluation of common lead data. To show the capability of the script, a common lead dataset for the Dlhá Dolina intrusion is presented and evaluated using CLEO. The timing of this evolved magmatic body can be constrained by the WR–Pb–Pb method to a minimum age of 231±6.5Ma.
