[R] Problem with fontsize of pie-chart in postscript file

[Daniel Hoppe]

Hi all,

I've a problem with the size of the labels of my pie-charts when I try to
write them to a postscript file. I need to increase the default size, so I
change cex (see below). On screen this works fine, but cex doesn't seem to
affect the postscript-file. Any suggestions?

Thanks a lot,

Daniel

Copy/Past-example (will try to write to c:/temp!):

labels <- c("I", "H", "G", "K", "V")
lineItems <- c(6252,943605,271207,517764,44108)
orders <- c(2084,226894,49218,164056,15809)
value <- c(1380425,87743481,35212459,76346384,10403599)
count <- c(52,17571,261,53270,843)

col = gray(seq(0.2,.8,length=6))

oldpar <- par()
par(cex=2)

#postscript("c:/temp/1.eps", onefile = FALSE)
pie(lineItems, labels=labels, col=col, density=15, angle = 15 + 10 * 1:6)
#dev.off()

postscript("c:/temp/2.eps", onefile = FALSE)
pie(orders, labels=labels, col=col, density=15, angle = 15 + 10 * 1:6)
dev.off()

postscript("c:/temp/3.eps", onefile = FALSE)
pie(value, labels=labels, col=col, density=15, angle = 15 + 10 * 1:6)
dev.off()
par(oldpar)
