Deepayan is an Associate Professor at the Indian Statistical Institute, and a member of R-Core. He is the creator of the lattice package, and the author of the corresponding book Lattice - Multivariate Data Visualization with R.
Visualization is an essential component of interactive data analysis in R. Traditional (base) graphics is powerful, but limited in its ability to deal with multivariate data. Trellis graphics is the natural successor to traditional graphics, extending its simple philosophy to gracefully handle common multivariable data visualization tasks. This course introduces the lattice package, which implements Trellis graphics for R, and illustrates its basic use.
