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? Cheers Chris Buddenhagen, Botany Department, Charles Darwin Research Station, Santa Cruz,Galapagos.

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. HTH, Marc Schwartz

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. Regards Knut with regards Knut Krueger http://www.biostatistic.de
