Abstract: The package PbIso is a free and open R toolbox for commonly used calculations and plots of Pb-Pb isotope data. In this paper, we review Pb isotope systematics and the calculations that are commonly used, such as model age, model source 𝜇 (238U/204Pb), time-integrated 𝜅 (232Th/238U), and initial Pb isotope ratios. These complicated equations are implemented into simple R functions in the package PbIso. In addition, functions are provided for generating model curves, geochron lines, and time-dependent slopes. This allows users to apply calculations to their data in a straightforward way, while providing transparency and flexibility of the calculations used. We have implemented some basic features of the PbIso package into an online shiny application (https://shereearmistead.shinyapps.io/PbIsoApp/), which makes it easy for users without any R experience to use these calculations with their own data and to generate plots.
