This alleged bug is Windows specific and occurs when using Windows metafile plots. The problem does not occur in a Linux version. It does not occur in the pt rintout when a graphic is saved to a postscript file under Windows. The problem came to light when using plotmath to label a plot with latitudes containing degree symbols. If expression(40 * degree) is used it is written on the default line for labels. If expression(paste(40 * degree, " S") is used it displced closer to the axis. Pasting any character (except "") has this effect. The following code illustrates the problem. par(mfrow =c(3,2)) # plotmath not used plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = seq(41 , 40, -0.5)) # plotmath not used but characters pasted into labels plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = paste(seq(41, 40, -0.5), "S")) # last label has no character component plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = expression(paste(41 * degree, " S"), paste(40 * degree, " ", 30 * minute), 40 * degree)) # last label has no plotmath component plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = expression(paste(41 * degree, " S"), paste(40 * degree, " ", 30 * minute), 40)) # last label has null character component plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = expression(paste(41 * degree, " S"), paste(40 * degree, " ", 30 * minute), paste(40 * degree, ""))) # last label has spaces character component plot(seq(-41, -40, 0.5), c(0, 1, 0), type = "n", xlab = "latitude", ylab = "", xaxt = "n", yaxt = "n") axis(1, at = seq(-41, -40, 0.5), labels = expression(paste(41 * degree, " S"), paste(40 * degree, " ", 30 * minute), paste(" ", 40 * degree, " "))) par(mfrow =c(1,1)) ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-devel
