I'm beginning to use the AVR backend. I ran into the problem, that newer (tiny1, mega0) µC as a tiny1614 are not supported. How do I add these to the AVR backend? Thanks!

Hi, (sorry for the wall of text; the issue here appears to be rather complicated) I'm seeing a somewhat strange case where checking whether an S4 object inherits from a parent class defined from another package with 'inherits' fails if that object is materialized through a call to 'load'. That's a mouthful, so I've put together a relatively small reproducible example

...inherits' and 'namespace:s4inherits'. Secondly, when R attempts to resolve the superclasses for an S3 class, the function 'methods:::.extendsForS3' is called. Tracing that code eventually gets us here: https://github.com/wch/r-source/blob/trunk/src/library/methods/R/SClasses.R#L255 Note that we reach this code path as the S3 class cache has not been populated yet; ie, this code returns NULL: https://github.com/wch/r-source/blob/trunk/src/library/methods/R/SClasses.R#L238-L240 So, the class hierarchy is looked up using this code: if(isTRUE(nzchar(package))) { wh...
