You need to get the hang of reading the online help. The information
required is actually there in ?dotchart --- it's just tersely and obscurely
expressed. A certain degree of optimism is required. You need to
***believe*** that the information is there; then ask yourself "What
could they possibly mean by what they have written that would tell
me what I need to know?".
This is how one should interpret the exhortation "RTFM" when it is
inflicted upon one.
After a few millennia it gets easier! :-)
