Hello, that appears to have fixed it. Thank you very much. I can now repeat the reported workflow and the image appears on the fifth (and subsequent) calls.
Great. Thanks for checking. Paul
That's great.
Just a little bump: I would encourage Simon (in his copious spare
time), or other interested members of R-core, to decide on a good
name for the argument (as a reminder, I prefer
'method=c("raster","image")'). Furthermore, I would strongly
encourage that "raster" be made the default behavior for the
development release of R ...
Unfortunately I just encountered a speed bump today - I had no idea that the Windows device doesn't even support transparent pixels. That needs to be fixed before we can make it the default...
See the table at the bottom of http://developer.r-project.org/Raster/raster-RFC.html for the full list of limitations.
Mea culpa - I had forgotten that the default for interpolate=TRUE (unfortunately) so all those dozens of warnings came from the fact that R was trying to interpolate on a device that doesn't support it. I stand corrected, transparent pixels are supported if interpolate=FALSE so image() should be safe. Thanks, Simon
