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)
plot(1:100,1:100) dev.off()
