one solution could be given by spliting your graph in two parts:
part_1 <- # take the desired four points subset #
part_2 <- # all rest points not to label
You will also need one vector with your names. I supose:
list <- c("B13", "G13", "K14", "N14")
text(part_1$x, part_1$y+.1, list)
Maybe you will have to set the limits (xlim and ylim) of your graph and
chage .1 to a more precise value.
Please, take care and ensure carefully reading of command internal help
(typing ?text, for example), the R's help-pages are very clear and didactic.
Be sure also, searching for previous questions already made in "r-help",
preventing double questions on basic isues, and be more specific possible
about your problem. If your data is from base, I could give you one better
Take care, Have a god job!
