Downloads show strong weekly seasonality with Saturday/Sunday lows; some packages show exceptional single-day spikes
Hierarchical clustering of packages based on co-download indicator matrix reveals which packages are used together
Analysis enabled by installr R package (by Tal Galili) which wraps Felix Schonbrodt's CRAN download tracking code
Top 100 spans statistics (MASS, lme4, survival), visualization (ggplot2, lattice, rgl), and database access (RODBC, RSQLite, DBI)
