Gaston Sanchez


I'm a statistician, data scientist, and lecturer in the Department of Statistics, at UC Berkeley. Professionally, I dedicate most of my time to:

  • authoring materials for teaching purposes (books, tutorials, slides, etc.),
  • using graphical displays to understand data with visualization,
  • applying multivariate methods for exploring, analyzing, and visualizing data in a context of multiple variables and high dimensionality,
  • reflecting about computational reproducibility topics and open science,
  • and helping researchers and scientists analyze their data.

Software


I'm a passionate R user as well as developer and maintainer of several R packages. All the code is available in my github repositories.

  • plspm provides a toolkit exclusively dedicated to Partial Least Squares Path Modeling (PLS-PM) analysis.
  • plsdepot a set of tools for performing Partial Least Squares (PLS) analysis of one or two data tables.
  • pathmox is dedicated to the Pathmox approach for obtaining segmentation trees in Partial Least Squares Path Modeling (PLS-PM) analysis.
  • arcdiagram is a minimalist package to help you plot pretty arc diagrams in R.
  • colortools is designed to help users generate color schemes and color palettes.
  • matrixkit is an R package that provides a first aid kit for some matrix operations commonly used in multivariate data analysis methods.
  • turner provides a set of handy functions to turn vectors (and lists of vectors) into other indexed data structures.
  • tester provides human readable functions to test characteristics of some common R objects.
  • cointoss is a toy package with simple functions for simulating tossing a coin.
