Dear all,
I am not sure what I am doing wrong, but I have some unexplained behaviour when
saving a lattice graph including text to a pdf file. The text seems to move
around. It must have something to do with the way coordinates are set in
devices other than jpg.
Any suggestions would be helpful
Willem
Here is some example code
setwd("c:/willem/research/misc")
today <- format(Sys.Date(),"%Y%m%d")
x <- runif(500)
y <- rnorm(500)
foo <- data.frame(x = x, y = y, z = rep(c("a","b"),250))
require(lattice)
xyplot(x~y|z,data=foo)
panel.text(370,470,"silly graph",cex=1.2,font=2)
savePlot(paste(today, "jpgplot",sep="_"),type="jpg") # this plots fine and text
is as on the screen
savePlot(paste(today, "pdfplot",sep="_"),type="pdf") # text has moved
pdf(paste(today,"pdfplot2.pdf",sep="_")) # no difference using pdf
xyplot(x~y|z,data=foo)
panel.text(370,470,"silly graph",cex=1.2,font=2)
dev.off()
# There is also no difference
