R help - Aug 2010 - problem with Bitmap

Hi All,

I am trying to run the following script but I am getting and error message
one=read.table("sample.txt",sep="\t")
bitmap(file="sample.JPG",type="jpeg",width=5,height=5,res=300,pointsize=10)
?Error in (st + 1):(en - 1) : argument of length 0?
plot(one$V1,one$V2)

I tried to google the error but did not find anything!
I have ghostscript installed and added to the path environment.

Your help is greatly appreciated,

Thanks,

The types of bitmap available depend on the ghostscript you have installed. 
Have you checked that yours handles jpeg?

What happens if you use the jpeg driver directly?

Hi,

if I use the jpeg driver directly like

one <- read.table("sample.txt",sep="\t") 
jpeg(file="sample.JPG) 
plot(V2 ~ V1,one) 

and it did not plot anything! why is that?

the version of ghostscript that I installed i from the following link



http://pages.cs.wisc.edu/~ghost/doc/GPL/gpl871.htm

and installed gs871w64.exe

thanks for your help
