Dear R help-list reader,

I would like to generate a plot which compares to states in a patient 
treatment, before and after. for this reason I have generated a vector
the first element in "before" corresponds to the first element in "after".
I would like and generate a dotplot with
before and after as x-scale, the elements of "before" and "after" on 
the y-scale and the corresponding elements connected with a line.

However, so far I couldn't figure out how to do this in R. If anyone 
as a suggestion, please let me know

Many thanks
