I am having issues with Ryacas errors.  I searched and found this error was
reported in 2006, but nothing since.
Loading required package: XML

CommandLine(1) : Expecting ) closing bracket for sub-expression, but got ^
instead
CommandLine(1) : Expecting ) closing bracket for sub-expression, but got Sin
instead

os:WindowsXP
Rversion:
R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows"

Platform: i386-pc-mingw32/i386 (32-bit)R-2.15.1

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

Its not related to R 2.15.1 since I used that on Windows to produce
the answers in my post. The error message you got does not indicate
the source of the problem. You could try using verbose=TRUE to get
more feedback and go over the troubleshooting section again. Look at
the whole section and not just the Windows part.

yacas(expression(Factor(x^2-1)), verbose = TRUE)
