I've been testing plotmath. But I'm getting some funny output one one computer. The problem is that characters are 'jumbled' and overstrike when symbols are introduced.
Sample code: mu <- 440.0 sigma <- 12.5 myx <- seq( mu - 4*sigma, mu+ 4*sigma, length.out=500) myDensity <- dnorm(myx,mean=mu,sd=sigma) # Here's one way to retrieve the values of mu and sigma and insert them into an expression t1t2 <- bquote (paste("Normal(", mu== .(mu), ',', sigma== .(sigma),")") ) plot(myx, myDensity, type="l", xlab="X", ylab="Probability Density ", main=t1t2) I have tested this code and it works on two desktop Fedora Linux 8 systems to make a nice figure, but on a Dell Laptop with Fedora Linux 8 and R 2.6.2, something funny happens: the characters "overstrike" each other. The Greek letter "mu" is printed several spaces to the left of the "(" that it is supposed to follow. I made an itty bitty picture of the figure title to show you: http://pj.freefaculty.org/R/plotmath_problem.png I can force in spaces to re-arrange the symbols so they do not overstrike. The following looks fine in the output. t1t2 <- bquote (paste("Normal ( ", mu== .(mu), ' , ', sigma== .(sigma)," )") ) ### Note spaces manually inserted above are needed, otherwise plotmath overlaps "l" of plot(myx, myDensity, type="l", xlab="X", ylab="Probability Density ", main=t1t2) What do you suppose is wrong?
