Dear list
It is possible to store expected output for tests and examples. From the
manual: "If tests has a subdirectory Examples containing a file
pkg-Ex.Rout.save, this is compared to the output file for running the
examples when the latter are checked." And, earlier (written in the
context of test output, but apparently applies here as well): "...,
these two are compared, with differences being reported but not causing
an error."
I think a NOTE would be appropriate here, in order to be able to detect
this by only looking at the summary. Is there a reason for not flagging
differences here?
The following is slightly related: Some compilers and static code
analysis tools assign a numeric code to each type of error or warning
they check for, and print it. Would that be possible to do for the
anomalies detected by R CMD check? The most significant digit could
denote the "severity" of the NOTE, WARNING or ERROR. This would further
simplify (semi-)automated analysis of the output of R CMD check, e.g. in
the context of automated tests.
Best regards
Kirill
