rCharts Remake of NYT

For those wondering if I have forsaken finance, the answer is no.  I just don’t think there is much to do in here besides watch and wait.  So more d3 and R as I try to distract myself from doing something dumb in the markets.

This time I used rCharts and slidify to  recreate another NYT visualization similar to what I did in 512 Paths to the White House.  Now with any cumulative growth time series that we build in R we can apply the template and create this amazing visualization.  Below is a screenshot.  Click here to see the live version.

I’ll be living the good life over the next week, so no posts until after the 4th of July.

dimple d3 and rCharts

I put together a quick tutorial combining my two favorite things: finance and interactive visualizations.  I show how to use the new dimplejs d3 library with rCharts to create some nice interactive plots of US Treasury yield data.   A screenshot is below.  Go here for the tutorial and here for the code to reproduce.

R Plotting Financial Time Series

In my little world of finance, data almost always is a time series.  Through both quiet iteration and significant revolutions, the volunteers of R have made analyzing and charting time series pleasant.  As a mini-tribute to all those who have helped, I wanted to write a short history of R time series plotting, specifically focusing on financial time series.  I have embedded below, but it will look much better if you go to Github pages version.

Rickshaw d3.js from R with rCharts

Shutterstock’s open source Rickshaw provides a very nice tutorial to get started building interactive time series d3.js charts with Rickshaw.  I just could not resist rebuilding the tutorial but this time ENTIRELY in R with the amazing packages slidify and rCharts.  I have embedded the tutorial below, but it will probably look much better if you go directly to the Github pages version.

The slidify and rCharts author Ramnath Vaidyanathan has done an incredible job and continues to perfect these fine tools.  They completely transformed my workflow and output by allowing both dynamic and interactive components that I can combine into a beautiful document.  Be sure to see him present to this NYHackr meetup  on June 17, 2013.
