[R] write values of points beside points in plot

[Katharina May]

Hi everyone,

is it possible to write a certain value beside a point in a plot?

I'm plotting the following:
plot(coefficient$intercept ~ coefficient$average_BM_leaves_needles,
main="intercepts ::: BM_leaves_needles",
     ylab="intercepts", xlab="average BM_leaves_needles per site [kg]")

and I want to have the value of coefficient$site_no written beside
each point within the plot (to recognize them)

sorry for troubling you with this question, but I somehow can't find
any information on it
(maybe because I'm not quite sure what to search for)

Thanks a lot,

          Katharina
