SirStatis is an R package that implements an extension of the DUAL-STATIS method to a SIR framework. It can be used to analyse multiway datasets in relation with a numeric target variable.

Role in the project: Author (Maintainer is Valérie Sautron)
Current version: 0.1 (April 2016)
Install SirStatis by first installing its dependancies
install.packages(c("ggplot2", "ggrepel", "expm", "MASS"))
and by then downloading the source package at this link.

NiLeDAM is an R package for dating monazites from measurements of triplets (U,Th,Pb) obtained by a microprobe technique. The implemented method is the one described in the article (Montel et al., 1996) and the package has been developed from the original programs made in basic language by Jean-Marc Montel (École Nationale Supérieure de Géologie, France). An example, kindly provided by Anne-Magali Seydoux-Guillaume is included in the package and is the one described in the article (Seydoux-Guillaume et al., 2012). Not maintained anymore

Other R programs


  • For the SFdS, I also developed a generic website to administer conferences (PhP/MySQL scripts). This solution is based on wordpress and includes a registration form (connected to a credit card plateform), an automatic sending of invoice by emails and tools to administer the participants and check the payment of registration fees. It also comprises a script that automatically generates the program of the conference based on MyReview. An example of my work can be seen on this page. The programs have been documented so that they can be used by any webmaster. The scripts are available on GitHub:
