A method to automatically download, install and load R packages that only requires the package name to be typed once. Credits: http://stackoverflow.com/a/8176099/1036500 & http://stackoverflow.com/a/4090208/1036500

auto-install-and-load-packages.R

list.of.packages <- c("xx", "yy") # replace xx and yy with package names
new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[,"Package"])]
if(length(new.packages)) install.packages(new.packages) 
lapply(list.of.packages, require, character.only=T)

Hi Ben,
This is great. I would only make a couple adjustments to the third and fourth line.

list.of.packages = c("xx","yy") # replace xx and yy with package names
new.packages <- list.of.packages[!(list.of.packages %in% installed.packages()[,"Package"])]
if(length(new.packages) > 0) {install.packages(new.packages)}
lapply(list.of.packages, require, character.only=T)

Otherwise this will only load packages that aren't installed. Whereas the goal is to load all packages, installed or not.

Thanks in advance
