Dear al,
I would like to thank you for your replies.
I have tried with graphics.off() but did not help too.
I am also sorry that my example was not reproducible
So this one
setEPS()
postscript(file="mytest.eps")
boxplot(test[30,1:500],test[90,1:500],test[150,1:500],test[210,1:500],test[270,1:500],test[330,1:500],test[390,1:500],names=c("1","3","5","8","10","13","15"),outline=FALSE,ylim=c(0.01,50),log="y",
xlab = "Number of Sensors/km^2",ylab="Percentage of Coverage Error Estimations
(log scale)",boxwex=0.5)
dev.off()
always saves to a eps file that works
while this one
setEPS()
postscript(file="mytest.eps")
boxplot(test[30,1:500],test[90,1:500],test[150,1:500],test[210,1:500],test[270,1:500],test[330,1:500],test[390,1:500],names=c("1","3","5","8","10","13","15"),outline=FALSE,ylim=c(0.01,50),log="y",
xlab = "Number of Sensors/km^2",ylab="Percentage of Coverage Error
Estimations (log scale)",boxwex=0.5,pars=list(whisklwd=0,staplelwd=0))
dev.off()
will create an eps file that is not saved. I think is the last part of the
boxplot pars=list(whisklwd=0,staplelwd=0) that creates that.
What should I do to debug this?

# Trashes
test<-exponper
setEPS()
postscript(file="mytest.eps")
boxplot(test[30,1:500],test[90,1:500],test[150,1:500],test[210,1:500],test[270,1:500],test[330,1:500],test[390,1:500],names=c("1","3","5","8","10","13","15"),outline=FALSE,ylim=c(0.01,50),log="y",
xlab = "Number of Sensors/km^2",ylab="Percentage of Coverage Error Estimations
(log scale)",boxwex=0.5)
# legend("topright",c("Exponential"))
dev.off()

Subject: Re: [R] postscript( does not save the plot
Sometimes when I have a script that does not close out a graphics
device correctly (using PDF), I sometimes have problems opening up the
file. I use the following command to make sure all graphics devices
are closed before generating plots after a script has not terminated
correctly:
graphics.off()
Try this command before generating your plots.
