Helmut,

For previous uploads you affirmed that you read the CRAN Repository Policy
which states

      [...]

Your package appears to violate that requirement.

As I wrote previously the statement continues with
"Limited exceptions may be allowed in interactive sessions if the 
package obtains confirmation from the user."

I'm not a native speaker of English but for me "should not write" != 
"must not write".

  I would fix the package.

I removed the automatic switch to "~/" if no path is given. As before I 
recommend in the man-pages to give the full path. However, I _still_ 
state that "~/" _can_ be used for convenience.
The package is used in a regulated environment. The output file contains 
an entire audit-trail (name of the user and system, version and date of 
the OS, R, all packages, functions used, time of execution, blablah). If 
the package would write to tempdir() I would have to add a warning in 
bold font of every man-page like "Execute the command tempdir() to find 
out where your result files reside. Copy the files to a safe location 
before you quit the R-session. If you fail to do so, your results will 
be lost."

Off topic: I don't like it that on Windows tempdir is located at 
"C:/Users/{Username}/AppData/Local/Temp/Rtmp..." I strictly separate my 
OSes (on C), software (on D), data (on E), backups (on F). Writing to 
the system disk is not what I prefer. However, in my installation "~/" 
resolves to "E:/Users/{Username}/Documents/"...
