I have a linux system with Fedora Core 2 and R-2.0.
I was comparing plots made with plot() and dotplot() and discovered a problem. Although the dots are positioned correctly, the numerical labels in the dotplot y axis are not correct.
I put copies here:
http://lark.cc.ku.edu/~pauljohn/R/plotTrouble1.jpg
That is the "correct" one from plot, with the higest value on y showing at 18.
http://lark.cc.ku.edu/~pauljohn/R/plotTrouble2.jpg
That is the dotplot one. The picture is basically the same, except the numbers on the y axis only go up to 8. But the dots are in the correct spots and the x axis is labeled correctly.
On the screen, the plots have white backgrounds, but the picture from the dotplot turns out gray. Why is that? Sometimes, if I run another lattice plot in the same session, the colors change to the dark background, and I suppose the same trouble is happening. Isn't trellis.par.set() going to remain in place for all following trellis plots?
Here's the code I used to make these 2 graphs.
x11(height=6.5,width=6.5) data2003<- subset(elaine1,POLCYEAR==2003) plot(data2003$OLDCRASH,data2003$RENUCYC)
modall <- lm(RENUCYC~OLDCRASH,data=data2003) abline(modall)
dev.copy(device=jpeg,file="plotTrouble1.jpg") dev.off() dev.off()
trellis.par.set(theme=col.whitebg(),height=9,width=6.5)
dotplot (RENUCYC~OLDCRASH, data=elaine1, xlab="ECR", as.table=T,subset=POLCYEAR==2003,
panel=function(x,y)
{
panel.dotplot(x,y,cex=0.2);
panel.lmline(x,y);
}
)
jpeg(file="plotTrouble2.jpg",bg="white",height=480,width=480) trellis.last.object() dev.off() dev.off()
I tried to force the ylim on the dotplot up to 18, but it just produced this even uglier result.
