Hi,

The messages are quite clear:

These are checks for undefined functions and variables. Sometimes,
non-standard evaluation causes this kind of message, but without a
link to the source code, it's impossible for me to assess the problem.
There are dozens of excellent posts about this topic though, so I
shall not elaborate on it any further.

This is mandatory since v3.4.0 and should issue a warning if I'm not
mistaken. Please, read "Writing R Extensions" carefully as the message
is exhorting you. This and further readings:
