New version of devtools: 0.8

2012-09-16 Hadley Wickham
We’re pleased to announce a new version of devtools, the package that makes R package development easy. The main features in this version are: A complete rewrite of the code loading system which simulates namespace loading much more accurately - this means using load_all is much closer to installing and loading the package. It also compiles and loads C, C++ and Fortran code in the src/ directory. All devtools command now only take a path to a package and default to using the working directory if no path is supplied.

We’ve just a made a change to the syntax for embedding MathJax equations in R Markdown documents. The change was made to eliminate some parsing ambiguities and to support future extensibility to additional formats. The revised syntax adds a “latex” qualifier to the $ or $$ equation begin delimiter. It looks like this: This change was the result of a few considerations: Some users encountered situations where the $equation$ syntax recognized standard text as an equation. Read more →
