Hi Simon,
Thank you for the information about the R image rendering issue in
Preview and Acrobat. I am happy to learn that my problem is not
related to R and Quartz.
As you suggested, I zoomed in and out with Preview but the white
lines did not disappear entirely. However, this is OK for the type of
analysis that I have performed.
The real problem that I have is converting it to a tiff file. I must
submit a tiff file to the journal where the image will be published.
When I use Preview for conversion, the image looks like a Scottish
plaid. The white lines are there but they look they are part of the
plaid.
Acrobat, on the other hand, is totally unacceptable. The image
shading disappears entirely and a series of dots appear within the map
boundary. The legends have no shading what so ever, thus converting it
to a tiff file won't work. I have successfully use this method for
transforming color R images in pdf to tiff.
Question: Is it possible to export or convert a R image directly to a
tiff file without going Preview?
Thank you,
Paul
