R help - May 2011 - scatter plot with Z value

Hi all, 

 

I would like to create a scatter plot of two variables (y, x)  whith third value
(z) written on the plot? After that i would like to add a line (Y=0.7*(x-20)) to
the graph.

 

I tried 

plot(x~y)

 

but there is no command for the third vairable to be shown on the graph

also i can't find a way to add a Y=x*(0.7-20) to the chart.

 

Thanks, m

I am sure you would have found answers to your questions if you would have
searched the mailing list archive 
(http://r.789695.n4.nabble.com/R-help-f789696.html)!

To get you started, have a look at:

?text   (for the z values)
?abline (for the line)
