The general nature of your question means there are a multitude of answers.
if you type '?abline' it will give you an example of a line drawn over a plot. type ?segments, ?lines, ?points, ?text and go through the examples and try them out The help pages to the base package 'grid' includes an introduction to using the various drawing mechanisms see ?par for the 'new' argument logical, defaulting to 'FALSE'. If set to 'TRUE', the next high-level plotting command (actually 'plot.new') should _not clean_ the frame before drawing "as if it was on a *_new_* device". Alternatively the 'lattice' package can produce a wide range of plots. Then try the various contributed documents that exist on the CRAN mirrors to further your knowledge. It's all there.

I'm looking for a way to add a line in a plot of a points that should lie along a particular line. Can I add a line to the 'plot()' function, maybe using 'abline()' so that the line is visible in the graph of 'plot()'? How? More generally, can I overlay plots over one another? Thanks.
