Gaston Sanchez


I'm an applied statistician, data scientist, and faculty member in the Department of Statistics, at UC Berkeley.

Among other things, I am very interested in:

  • multivariate methods for exploring, analyzing, and visualizing data in a context of multiple variables and high dimensionality.
  • the use of graphical displays to understand data with visualization.
  • topics about computational reproducibility and open science.
  • helping researchers and scientists analyze their data.

This website is my personal space where I try to declutter my ideas and put all my work in order (which is easier said than done). If you find any valuable resources here (which I'm pretty sure you will) please consider helping me with my wishlist.

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.

Blog


Occasionally, I like to talk about data analysis, visualization, statistics, R and related stuff in my blog Data Analysis Visually EnfoRced.
