Hi 
 I'm want to obtain a  plot of 1200dpi tiff format, but I met some difficulty.
Could anybody show me some examples about it? 
  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",  :

2: In tiff(file = "shaw.tiff", width = 8.6, height = 8.6, units = "cm",  :
