configuring rjava

rjava-on-history-vm.md

a note on getting rJava to work with Matt's HistoryVM

At the terminal:

$ sudo apt-get install openjdk-7-*

$ sudo update-alternatives --config java

select openjdk 7 when prompted. then:

$ sudo R CMD javareconf

Then in R you can

install.packages('rJava')

without issue.
