The "type" argument to plotting functions determines the type of plot
(plot lines or points or both or ...).  To specify the type of line you
need to use the "lty" argument.  See the help page for "par"
(?par) for
details on the types of line you can use (also "lwd" is the width of
the
lines).  

But you should note that the human eye is drawn to contrasts and
therefore using dashed and dotted lines will sometimes distract the
viewer or require more work to understand the main points of the plot.

Have a look at the lty parameter. It's documented in ?par. If I
understand your question correctly, you may also be interested in
segments() to actually draw the lines (or maybe abline()).
