R help - Jul 2009 - labelling points plotted in a 2D plan

I created a 2 D plan:
> plot(range(-2.5,0.95),range(0.00,1.00),type="n",axes=TRUE)
I made  a projection of points with their coordonates (X,Y) in that plan
> fullpoints=read.csv2("fullpoints.csv",h=T)
> plot(fullpoints)

The points are listed in that .csv file it is organized this way:


0,48875 0,142857143
0,409 0,142857143
0,45611 0,25
0,49833 0,222222222
0,61158 0,125
0,5709 0,125
0,53266 0,125
etc...

Each line is for the coordinates of a point.


Now I want to display a label "a" or "s" for each point that
will be shown
graphically in the plot?

for instance:
0,48875 0,142857143 > labelled a
0,409 0,142857143 > labelled a
0,45611 0,25        > labelled s
0,49833 0,222222222 > labelled a
0,61158 0,125       > labelled S
0,5709 0,125       > labelled s
0,53266 0,125       > labelled a

etc....



How to proceed? thanks IA.

Hi Khaled.

I believe using "text" on an empty plot would do the trick...

Hello Tal!
Nothing showed up when I used those commands!
The plot still shows dots with no labels!
Thanks
