Hi R-help list What is the threshold for the `useRaster` argument of graphics::image() to decide whether a grid is "regular" or not (i.e. the usage of useRaster=T is allowed or not). My `dev.capabilities("rasterImage")$rasterImage` is "yes".
I could not find this information in the internet. I also could not find the source code of the graphics::image() function (I would answer the question by myself then). Where can I find the source code? Thanks a lot for any help and kind regards, Chris packageDescription("graphics") Package: graphics Version: 4.0.2 Built: R 4.0.2; x86_64-pc-linux-gnu; 2020-06-22 08:33:40 UTC; unix [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
