See ?plotmath: There is "partialdiff"! text(1.6, 1, expression(slope == frac(partialdiff * f(hat(theta)), partialdiff * hat(theta)))) Uwe Ligges > dev.off() > > plot(NA, xlim=c(-3,3), ylim=c(0,1.6), xlab="", ylab="", tck=-0.015) > > text(1.6, 1, expression(paste("slope = ", frac(paste(" f( ", hat(theta), > " )"), hat(theta))), sep=""), adj=0) > > text(2.25, 1.03, "\\pd", vfont=c("sans serif","plain")) > > text(2.3, 0.934, "\\pd", vfont=c("sans serif","plain")) > > > > Thanks. > > > Charles Annis, P.E. > > [EMAIL PROTECTED] > phone: 561-352-9699 > eFax: 614-455-3265 > http://www.StatisticalEngineering.com > > > ______________________________________________ > R-help@stat.math.ethz.ch mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
