# Gaston Sanchez

I'm a statistician, data scientist, and lecturer in the Department of Statistics, at UC Berkeley. I tend to spend my time around:

• 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,
• and helping researchers and scientists analyze their data.

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

## Teaching

Some of the courses I've taught in the Department of Statistics, UC Berkeley.

• Stat 2: Introduction to Statistics
• Stat 20: Introduction to Probability and Statistics
• Stat 131A: Introduction to Probability and Statistics for Life Scientists
• Stat 133: Concepts in Computing with Data
• Stat 154: Modern Statistical Prediction and Machine Learning
• Stat 159: Reproducible and Collaborative Statistical Data Science
• Stat 243: Introduction to Computational Statistics

## 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.

## Blog

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