I think it should work on any reasonable machine, but it is worth pointing
out that there are 4 separate tiff() devices:
Unix, X11
Unix, cairo,
Mac OS X, quartz,
Windows, graphapp
and once again we really did need the OS information asked for in the
posting guide. As I recall Ben uses one of the first two, and the error
message looks like the fourth.
Also, the file size will depend on the contents, and the example was not
reproducible. (It is likely to be ca 48 or 64 Mb, though, depending if
transparency is used.)

Hi
I'm want to obtain a plot of 1200dpi tiff format, but I met some difficulty.
my code:
##############################################
tiff(file="shaw.tiff",width=8.6,height=8.6,units="cm",res=1200,pointsize=10)
plot(bal100,type="l",pch=20,col="red",lwd=1.5,axes=F,xlim=c(1,5),
ylim=c(0,0.3),ann=F)
par(new=T)
plot(bal80,type="l",pch=20,col="blue",lwd=1.5,axes=F,xlim=c(1,5),
ylim=c(0,0.3),ann=F)
....
##################################################
source("plot_data6.txt")
Error in tiff(file = "shaw.tiff", width = 8.6, height = 8.6, units = "cm", :
unable to start device
In addition: Warning messages:
1: In tiff(file = "shaw.tiff", width = 8.6, height = 8.6, units = "cm", :
Unable to allocate bitmap
2: In tiff(file = "shaw.tiff", width = 8.6, height = 8.6, units = "cm", :
opening device failed
Worked for me. Do you have memory or disk space problems?
I would try reducing the resolution a bit to see if that works
(I know that won't solve your problem but it will help
diagnose it).
tiff(file="test.tiff",width=8.6,height=8.6,units="cm",
res=1200,pointsize=10)
