You could try to use another argparse formatter. In particular one could try ArgumentParser(formatter_class="argparse.RawTextHelpFormatter)" which "maintains whitespace for all sorts of help text, including argument descriptions." You may need to manually enter a bunch of newlines and spaces where you want them but could give you the low-level formatting control you want.

If you switch from {argparse} to {optparse} then it is possible to write you own custom help formatter in R.
