If something goes wrong with your code, R tells you. We have to admit it: These
error messages can range from mildly confusing to completely incomprehensible
if you’re not used to them.
fortune(350) regarding the on-line help is also inspiring
You need to get the hang of reading the online help. The information required
is actually therein ?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?".
