This is a verbatim translation of the original pedtodot implemneted in Bash/awk in contrast to pedtodot which was largely a mirror. To check independently, try xsel -i < <(cat pedtodot_verbatim.R) or cat pedtodot_verbatim.R | xsel -i and paste into an R session.

Note

Adapted from Bash/awk script by David Duffy
