Command I am using for the plot: plot(Raw[][Plate==101]~well[][Plate==101], xlab="Well", ylab="Raw", main="Plate 101") I only want to label points on the graph where well equals B13, G13, K14 and N14 with the name of the well.

I can use the text() command to label all points but how do you specify only to label those four specific points on the graph? -- View this message in context: http://r.789695.n4.nabble.com/How-to-label-specific-points-on-a-scatterplot-tp3654697p3654777.html Sent from the R help mailing list archive at Nabble.com.

rstudent,
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")
So
plot(part_1$x, part_1$y)
text(part_1$x, part_1$y+.1, list)
points(part_2$x, part_2$y)
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
answer.
Take care, Have a god job!
