`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.

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")
```

For vignettes, overview, pointers to additional information, installation instructions and a sample session see https://r-cas.github.io/ryacas0/.

Yacas documentation can be found at http://yacas.readthedocs.org/

Once `Ryacas0`

is installed, pointers to additional information can be found with these R commands:

```
library(Ryacas0)
package?Ryacas0
```

The package contains stripped-down yacas distribution. For the complete yacas source code see https://github.com/grzegorzmazur/yacas/ . For more information on yacas see http://www.yacas.org/.
