Issue of binning_rgr()

[choonghyunryu]

Problem and Cause

The following error may occur when applying binning_rgr() in a specific case of discrete data with a large number of cases.

Error in order(fpoints_tio) : argument 1 is not a vector

The cause of this problem is an error message from funModeing::discretize_rgr() that the function uses.

Solutions

To solve this problem, I have to report the issue to the author of funModeing::discretize_rgr() or modify the function at the source level and use it.
