Well, actually only one [the other went to R-core alone]
Here it is :
From: Martin Maechler <maechler@sophie>
To: R-bugs
Subject: plot math - segfault and "frac", "^" bug(s)..
Date: 8 Dec 1999 12:50:44 +0100
This is in R versions 0.65, 0.90.0, and the current "pre-release",
both on Linux and Solaris
[with x11() , but most probably not device dependent].
The following shows it all :
plot(1,type='n')
## Frac doesn't shrink properly...
text(.7,1.3, expression( frac(7,4) == 1 * frac(3,4)), cex=1)
text(.7,1.2, expression( frac(7,4) == 1 * frac(3,4)), cex=3)
## Bug in precedency rule of "^" :
text(.7, 1, expression( Phi^{-1}(frac(3,4))),cex=3)
text(1.1,1, expression( {Phi^{-1}}(frac(3,4))),cex=3)
## This segfaults :
text(.9, 1, expression( Phi^ -1 (frac(3,4))),cex=3)
