I am wondering if someone could cast some the box plot function. I have been having trouble manipulating boxplot to display the x & y axes in bold. I had the same problem with the x & y labels but managed to get around that with the "mtext" function. The below code is what I have thus far..... boxplot(SV ~ Rater, data=volumes, xlab=NA, ylab=NA, cex=0.75, col="lightblue") title("Volume versus Rater", cex=1.2, font=2) mtext(expression(bold(paste("Volume"))), side=2, line=3, cex=1.2) mtext(expression(bold(paste("Raters"))), side=1, line=3, cex=1.2) Ideally, I would like to be able to automatically (based on the data in the input file) display in bold the values on the y-axis since I am trying to run this code on several different sets of data. However, if the resolution to this issue requires me to manipulate the code based on the y-values in the each input file that'll work too. Thank you kindly in advance, Jim Brindle [[alternative HTML version deleted]]
