[R] Ryacas

2012-09-04 Thread Jason Romine 
I am having issues with Ryacas errors.  I searched and found this error was
reported in 2006, but nothing since.

 library(Ryacas)
Loading required package: XML
 yacas(expression(Factor(x^2-1)))
[1] Starting Yacas!
CommandLine(1) : Expecting ) closing bracket for sub-expression, but got ^
instead
   yacas(D(x)Sin(x))
CommandLine(1) : Expecting ) closing bracket for sub-expression, but got Sin
instead
 

x - Sym('x')
   (x+1) * (x-1)
CommandLine(1) : Error parsing expression, near token +
 



os:WindowsXP
Rversion:
R version 2.15.1 (2012-06-22) -- Roasted Marshmallows
Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: i386-pc-mingw32/i386 (32-bit)R-2.15.1
Yacas version:1.0.63

Any suggestions appreciated,
Jason

Thank you Gabor.  I tried to exhaust all troubleshooting solutions listed on
the site you suggested prior to posting my question.  Perhaps you could
share what this error is stemming from.  Interestingly, on another machine I
have no issue with it when I run R 2.10, whereas when I try Ryacas with R
2.15.1 on the same machine the error shows up.  

Thanks,
Jason
