  You probably want to use the 'text' function, but you have to set up 
the plot first, since 'text' adds to plots. EG:

plot(c(0,1),c(0,1),type='n')

text(runif(10),runif(10),'Random')

The text is by default centered on the x,y location, but you can change 
this with the adj parameter.

The text can be a vector, and it is recycled to the length of x,y:

text(runif(10),runif(10),c('Foo','Bar'))

see help(text) for more.
