[R] overlapping labels

Good evening,  

I am trying to add labels to the point of a simple plot, using the text() function; the problem is that sometimes, if two points are too close to each other, labels overlap and are no longer readable. I was wondering whether there are options that I can use to prevent this overlapping (by, for example, placing labels alternatively above and below the plotted curve), or whether I should use another set of graphical functions (grid or lattice packages). Does anybody have suggestions?  

Thank you,  

Filippo Biscarini  

PS: These are the lines of codes that I have been using to generate the plot.

plot(
 prova$x,
 prova$y,
 type="b",
 mar=c(0.5,0.5,0.5,0.5),
 xlab="basepairs",
 ylab=""
);
 

text(

 prova$x,
 prova$y,
 prova$lab,

 pos=3,
 offset=2,
 cex=0.5
);
