Minor issue, but the following changed as of R3.3.2 from:
> a <- function() b()
> a()
Error in a() : could not find function "b"
To (at least in R Under development (unstable) (2016-11-20 r71670)):
Error in b() : could not find function "b"
Notice the "Error in **b**() :" part. The original error message
seems more correct to me, although I can see how you can argue for either one.
Best regards,
B.

[Rd] Changes in error reporting in r-devel
Its a compiled/interpreted difference. At the moment a small function like this is only compiled on the second call. That is in flux as we tune the JIT. But we should try to get rid of the difference. I actually prefer seeing the more specific call b() since you can get the larger context from traceback(), and showing b() is more consistent with argument errors in builin calls.
