Statistical Toolbox for Radiometric Geochronology.

IsoplotR

IsoplotR is a free and open-source substitute for Kenneth Ludwig's popular Isoplot add-in to Microsoft Excel. This Github repository contains the code for IsoplotR's core commands. A graphical user interface is provided in a separate repository at https://github.com/pvermees/IsoplotRgui.

Installation

You must have R installed on your system (see https://www.r-project.org/). The most recent stable version of IsoplotR is available from CRAN at https://cran.r-project.org/package=IsoplotR and can be installed on your system as follows:

install.packages('IsoplotR')

Alternatively, the current development version of IsoplotR can be installed from Github with the remotes package:

install.packages('remotes')
remotes::install_github('pvermees/IsoplotR')

Example

Once installed, IsoplotR can be loaded into memory by entering the following code at the R command prompt:

library(IsoplotR)

Now we can issue IsoplotR commands to R. For example:

setwd(system.file(package='IsoplotR')) # navigate to the built-in data files
RbSr <- read.data('RbSr1.csv',method='Rb-Sr',format=1)  
isochron(RbSr)
