Dear colleagues,
Saving a plot with pdf gives a very nice result:
pdf("myplot.pdf")
par(font=1,family='serif')
plot(pressure)
dev.off()
Doing the very same with other formats (png, jpeg, tiff) gives far
worse results. Is there anything to do to make a plot in some other
format than pdf look like the pdf? Hardly any journal accepts pdf
files for figures, and most do accept png and jpeg -- so no matter
what I think about this, I must follow this rule. What can I do, then?
I am using R 2.9.0 for Windows XP.
Many thanks in advance,
Wolf
Hi, postscript should do, "*.eps" specifically.
x=rnorm(100,0,1)
e=rnorm(100,0,1)
y=x+e
postscript("myeps.eps")
plot(y~x)
dev.off()
Cheers,
Daniel

Betreff: [R] Graphical output format
Dear colleagues,
Saving a plot with pdf gives a very nice result:
pdf("myplot.pdf")
par(font=1,family='serif')
plot(pressure)
dev.off()
Doing the very same with other formats (png, jpeg, tiff) gives far worse
results. Is there anything to do to make a plot in some other format than
pdf look like the pdf? Hardly any journal accepts pdf files for figures, and
most do accept png and jpeg -- so no matter what I think about this, I must
follow this rule. What can I do, then?
I am using R 2.9.0 for Windows XP.
Many thanks in advance,
Wolf

What can I do, then?Either create the graphs with very large width and height (usually corresponding to 600dpi); scaling may be tricky if you use this way, check the pointsize parameter. Or, my preferred way: create pdf, and use Ghostview to make the conversion. There is nice utility called GhostFriend that helps in getting the horrible parameters right and processing whole directories. Dieter
Thank you, Paul. Postscript, however, does not have to be what I need for two reasons. First, it does not accept some special characters from foreign languages (exactly like PDF). Second, not too many journals accept it. So from your -- and Daniel's -- reply I understand other formats will not work well? (Byt bad I understand the quality of the images, which is perfectly seen on fonts).

What can I do, then?What journals are you looking at? I see the opposite in medicine, epidemiology, and biostatistics, with the majority of journals requesting pdf or eps (which can easily be created by R or by running a simple conversion from pdf).

I always had the impression that pdf is the most comprehensive in foreign character support. Dieter
