Major update of Ryacas (R Interface to the Yacas Computer Algebra System)

We (Søren Højsgaard and I) are preparing a new major release of Ryacas (GitHub). It will have a new interface to yacas that is thinner, cleaner and more robust. It relies on yacas’s RForm() function rather than an OpenMath XML interface. It also means that the API has changed in Ryacas: new functions are introduced and old ones deprecated. Before showing the new API, let us first mention that a legacy version of Ryacas is available at GitHub.
