I noticed the following difference in parse(text = ...) between R
2.4.1 and R 2.5.0.
===
> parse(text = "\"^\" (x ,2 )")
expression(x^2)
> R.version.string
[1] "R version 2.4.1 Patched (2006-12-30 r40331)"
====
> parse(text = "\"^\" (x ,2 )")
expression("^" (x ,2 ))
> R.version.string
[1] "R version 2.5.0 RC (2007-04-16 r41194)"
====
Ryacas was depending on the behavior in R 2.4.1 so the new
behavior breaks it.
Is this intentional? a bug? How do I get the R 2.4.1 output
from R 2.5.0 ?
