You could use the ryacas (CAS) package: http://code.google.com/p/ryacas/ and/or http://cran.r-project.org/doc/vignettes/Ryacas/Ryacas.pdf e.g: > library(Ryacas) > yacas(expression((1/2 + 1/8) * 1/2 )) [1] "Starting Yacas!" expression(5/16) > Stefan > Something that would calculate something like: > > (1/2 + 1/8) * 1/2 = 5/16 > > without ever transforming to 0.5 and 0.125? > ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
