$Hazardous and Benign Space Objects: Orbits in the Solar-Ecliptic Reference Frame$

In two previous posts in this series I have wrangled NEO orbital data into R and then solved Kepler’s Equation to get the eccentric anomaly for each NEO. The final stage in the visualisation of the NEO orbits will be the transformation of locations from the respective orbital planes into a single reference frame. Reference

There’s a new version of my assertive package, for sanity-checking code, on its way to CRAN. The release has been delayed a while, since my previous attempt at an upload met with an error that was only generated on the CRAN machine, but not on my own. The problem lay with some code designed to

It’s no secret that I enjoy basketball, but I’ve often wondered about the carbon footprint that can be caused by 30 teams each playing an 82-game season. Ultimately, that’s 2460 air flights across the whole of the USA, each carrying 30+ individuals. For these reasons, I decided to investigate the average distance travelled by each NBA

## reshape2 1.4; Kevin Ushey joins Rstudio

May 9, 2014
By

reshape2 1.4 is now available on CRAN. This version adds a number of useful arguments and messages, but mostly importantly it gains a C++ implementation of melt.data.frame(). This new method should be much much faster (>10x) and does a better job of preserving existing attributes. For full details, see the release notes on github. The
