This follows the historic convention used by
aqp::plotSPC() looking for "hzname" or other column names containing the regular expression "name". If the pattern "name" is not found, the pattern "desgn" is searched as a fallback, as "hzdesgn" or "hz_desgn" are other common column naming schemes for horizon designation name.
Character containing horizon designation column name.
