MLB Pitcher Values
Not the start Blue Jays fans were looking for. With a 6-9 record at the time of publication they already trail Boston (led by reviled ex-BJ manager, John Farrell) by 4.5 games. The batting has been particularly anemic but the pitching – particularly the starting rotation – has also been a concern I have whipped up a Shiny App comparing Salary...

Shiny App for CRAN packages
Over the past few days, I have been introduced to a few new-to-me R packages, via some comments from the Shiny guys and the R-bloggers site. This seems a rather haphazard way of acquiring knowledge and I cannot be alone in thinking that this is not the most productive way to become aware of new/better packages.

Not only CRAN downloads and Shiny … but also .. rCharts
I have been meaning for some time to get stuck into the rCharts package which provides an interface to many Javascript graphic libraries. These offer rich charting capabilities with interactivity and a great deal of customization.
