Ryacas0: Legacy version of Ryacas

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.

Install from github

To build and install from github using R 3.3.0 (or later) and the R devtools package 1.11.0 (or later) run this command from within R:

# without vignettes
devtools::install_github("r-cas/ryacas0")

This will not install the vignettes. If you want to have those included, then instead run

# with vignettes
devtools::install_github("r-cas/ryacas0", 
                         build_opts = c("--no-resave-data", "--no-manual"))
# after installation
help(package = Ryacas0)
# or
vignette(package = "Ryacas0")
