[Rd] Computer algebra in R - would that be an idea??

Sounds really nice... Due to a not-so-particularly-nice summer weather in
Denmark, I have started writing a little package called 'yacasR' which
communicates with Yacas through a socketConnection (on windows, I don't know
how general this communication method is??). I'll try to 'polish'
the package a bit more within the next few days and afterwards post it somewhere
(not on CRAN, though). If the yacasR idea can fly, I hope more people will
contribute to the package...

However, it would be really good if some of you who know more about the
technical stuff, could find a way of making Yacas communicate with R more
smoothly...

Best regards
S?ren

Hi,
I am the maintainer of Yacas. I decided to join this mailing list
after having heard that
the option of linking R to Yacas was being discussed. Please don't
hesitate to ask
if you have questions, I will try to find the time to help.
