Answer 1

Here is a short piece of code to answer some questions. I will keep adding to my answer when I find time.

library(XML); library(ggplot2);

url = 'http://cran.r-project.org/web/packages/available_packages_by_name.html'
packages = readHTMLTable(url, stringsAsFactors = F)[[1]][-1,]

# histogram of number of characters in package name
qplot(nchar(V1), data = packages)
