That character list in your extract from R-exts.pdf is a list of
non-special characters. And [ and % are in there.
It's clarification of three sentences previous, which says:
the characters ‘’, ‘*’, ‘:’, ‘/’, ‘’, ‘’, ‘?’, ‘\’, and ‘|’ are
not allowed in file names
I also have some functions that also have those special
characters defined in those files exported in NAMESPACE.
I use the following command to install. And I get no warning or errors.
R CMD INSTALL -d -l my_custom_dir my.pkg
I then load the package. I get the following errors and warnings. I
changed a file to one without these special characters. Then the
corresponding warning/error disappears. Is it the case that there
should never be files with special characters as names?
library(my.pkg)
Error in namespaceExport(ns, exports) :
undefined exports: %is%
In addition: Warning message:
S3 methods ‘[.set’ were declared in NAMESPACE but not found
Error: package/namespace load failed for 'my.pkg'
Have you done an R CMD check on your package? I suspect a problem in
your NAMESPACE file, but it's not related to special characters.

Re: [Rd] filenames with special characters in the R/ directory of a package?
'Writing R Extensions' does say what names are allowed in the R
directory (at the start of section 1.1.3 in section-numbered formats).
To wit
The R subdirectory contains R code files, only. The code files to be
installed must start with an ASCII (lower or upper case) letter or
digit and have one of the extensions .R, .S, .q, .r, or .s.
'[.set.R' does not meet that rule, and so is skipped. This is not
something R CMD check reports, since the wording implies that other
names can be used for files to be not installed.

Re: [Rd] filenames with special characters in the R/ directory of a package?
It is strange to me why the filename must start with a letter or
digit, while the following characters can be something like '['. Is
there a reason why it is designed in this way? So that I can
understand the design principle rather than memorizing the facts
derived from the principle.
