Under the above given setting the following warning message appears when e.g. LDARep is executed:
1: In sprintf(...) : one argument not used by format 'Exporting objects to package env on master for mode: %s'

If you are running LDARep locally, however, the following message should appear:
Exporting objects to package env on master for mode: local

This is a warning resulting from parallelMap::parallelExport, explicitly from the line
showInfoMessage("Exporting objects to package env on master for mode: %s", mode, collapse(objnames)).
There is only one conversion specification %s, but two arguments, which results in the warning.

This will not be fixed, because the development of parallelMap is retired and this is an unwanted behavior that does not necessarily need to be corrected. Instead, the ldaPrototype package will replace parallelMap with the future package in the long run.
