Hi, Sorry for the high volume. I'm finding new problems as I resolve old ones.
The only remaining issue is modifying the boxplots generated by my function. I have found the various parameters like font.lab, font.main, etc., in the manual, but I cannot figure out where to introduce them. The function creates boxplots in a quartz window. quartz(width=6,height=5,dpi=200) boxplot(tframe[,x2] ~ tframe[,x1], font.main=1, main=gtitle,xlab=names(tframe[x1]),ylab=names(tframe[x2]), notch=FALSE, varwidth=TRUE) Thank you in advance.
