How to find detritis rejected by "R CMD check" on Debian?

Hello:


  ????? How can someone help me find and fix the following, contained in
00check.log on Debian for "https://github.com/JamesRamsay5/fda":


NOTE
Found the following files/directories:
  ? ?fdaMatlabPath.m?
* checking for detritus in the temp directory ... OK


  ????? See:

That would have resulted from running the example in ?fdaMatlabPath.

You could stop that from happening in a test by using

if (interactive())
   fdaMatlabPath()

but it still potentially wipes out a user's file.  Can't you ask the 
user for the filename to write to, and have the example write to 
tempdir() instead of the current directory?
