high resolution images for publication

Dear all

I am using R to produce ordinations library(vegan) and the plot function
produced looks great on the screen but when I send it to jpg or pdf or eps
the resolution is not so good. Can you tell me how to get high resolution
images out of R for publication?

It would be helpful to see the actual code that you are using, as is
asked for in the Posting Guide.

For publication, it would be rare to want to use a bitmapped format such
as jpg/png.

pdf and eps are vector based formats and would be generally preferred
over the above.

I can only hazard a guess to consider that perhaps your height and width
arguments for pdf() and/or postscript() are not set properly, as there
are no other resolution based settings for those formats. By design, the
output resolution is target device dependent.

Please provide the code that you are using and we can respond with more
specific guidance.

I tried to fix that problem weeks ago.
The journal wants Tiff files in high resolution or EPS files - no PS files.
The best solution was to use the postscript files from the R graphic
device (right mouse save as postscript)
After this I converted the files with Ghostscript and GSViev in a
suitable file format.
and after the submission was ready I tried to submit the postscript file
... It worked better than all the other.

Maybe you should also try to use the PS-files.In our case we were ale to
look to a PDF file after sending the file whether the submission is ok
or not.
And if it was ok the submission was sent to the journal.

Therefore I tried all graphic formats before the regular submission.

300 dpi PNGs work quite well in my experience, and not many will take
PDF.  It helps if you know what size they're to end up and make plots
accordingly to avoid any need to resize.  JPGs are good for
photographs, but not for line work.

For publishers who insist on TIFF format, it should be noted that
despite the fact that they're very large, they compress well and can
be decompressed by the publisher.
