Building Interactive Graphs with ggplot2 and Shiny Review

ruby mac finance r review

In 2009, I was asked to graph some data. It was not a lot but it was painful trying to get it done within the day. Back then there weren’t a lot of options for graphing data and I had to fix bugs of Google charts Ruby gem.

ruby mac rails

Snow Leopard includes Ruby and Rails by default if you install XCode. The version is 1.8.7 and 2.2.2 for each, respectively.
