Ryacas0 is a legacy version of Ryacas.

Ryacas0 is an R interface to the free yacas Computer Algebra System. Ryacas0 allows one to send R expressions, unprocessed yacas strings and certain other R objects to yacas process from R and get back the result. It also has facilities for manipulating yacas strings and R expressions destined for yacas processing.

It can be used for exact arithmetic, symbolic math, ASCII pretty printing and translating R to TeX.
