[R-pkg-devel] inconsistent behavior between R CMD check and interactive use

[Richard M. Heiberger]

I am seeing this in

platform       x86_64-w64-mingw32

I also saw this in 2019-12-03 r77513


In my interactive use I set
> Sys.setenv("_R_CLASS_MATRIX_ARRAY_"="true")
to match what --as-cran does for class(matrix(1))

There are two problems, unrelated I think.

1. I have an example which works correctly in interactive use and which
shows an error under R CMD check.  The error message is the one we now expect
when class(matrix(1)) is just "matrix".  The error should not be
triggered when the class
is c("matrix","array")


2. I export many functions.  Several are not handled correctly during
R CMD check testing.
They appear in the NAMESPACE in the source, and also in both the
Rcheck 00_pkg_src and the Rcheck built package.
Yet, when those functions are called during the testing of the
examples, they aren't visible.
An ls() call inserted into the \examples{} section does not include them.
The functions are visible and work correctly during interactive use.


I am running a WIndows 10 system inside a Parallels Virtual Machine on
a Macintosh.

Has anyone else seen similar misbehavior?
Or can suggest a repair?
