Hello, First, I would like to congratulations for very cool package! It's very nice idea!... Secondly, Is there a way to send R'objects (variables) to yacas and make symbolic operations?? for example:
d <- diag(3) a <- "A" yacas( d * a ) Thanks, Cleber Borges Gabor Grothendieck wrote: >Ryacas is an R interface to the free yacas computer algebra >system.
