I'd love to emphasize the key point M(2.1, sin(2.1)), and just write
a point coordinate by the side of M .How to do that easily?
Have you worked through the examples on the help(tex
Thanks David, for your prompt reply.
Ok... just avoid this mess.
I'd love to emphasize the key point *M(2.1, sin(2.1))*, and just write a
point coordinate by the side of M .How to do that easily?
By the way, if there is another point *N(2.2, sin(2.2))*, will M and N
conflict (overlap) each other?

Now, I added a specific line (red line in the picture at
http://www.visionopen.com/Rplot.png) by using abline.
However, I still love to add the X-coordinate "2.5" out
