The Ryacas package was formerly a client-side interface to YACAS (Yet Another
Computer Algebra System). I couldn't get either version 1.0.63 or version 1.4.2
to accept Ryacas' client messages on the R 2.3.4/OSX10.11.3 platform, despite
being able to run YACAS as a standalone package. I contacted Gabor Grothendieck
who was in correspondence with Grzegorz Mazur who had recently bolted on a
recent version of YACAS to the package itself, obviating any server-client
fragility. It seems to "just work" on my system. The only requirements would be
current versions of XCode, Rcpp, XML, and devtools:
if( require(devtools) ) {
devtools::install_github("ggrothendieck/ryacas") }
Gabor has suggested that interested useRs may want to take this racehorse out
on the track for further testing.
