Label specific points in a plot
Here I have two vectors: "Pr" and "Z"
here is my code:
Z=seq(1,10,by=0.5)
Pr=lapply(Z,functionZ)
plot(Z,Pr,main="CAT Bond Price with increasing attachment points",xlab="Attachment Point",ylab="Price")
grid(nx = NULL, ny = NULL, col = "blue", lty = "dotted")
I want to select only two points in the plot, namely those where Z=5, and Z=7.5 and label them as "Class A" and "Class B" respectively. How can I do that?
r plot label

can you put i what functionz is so we can reproduce this? Also I know ggplot has a way to label only specific things, and it looks really nice too

Or just skip the function entirely and make up some simple number: x 1-5, y: 1-5, label 2 and 4...

Your example is not reproducible, so I made up some random data and plotted with ggplot:
Z=seq(1,10,by=0.5)
Pr <- 1:19
L <- c("Point1", rep(NA, 17), "Point19")
df <- data.frame(Pr, Z, L)
library(ggplot2)
ggplot(aes(x=Pr, y=Z, label=L), data=df) +
geom_point() +
geom_label() +
xlab("Attachment Point") +
ylab("Price") +
ggtitle("CAT Bond Price with increasing attachment points") +
theme_classic()
You just define which ones you want to show labels for in a separate labels column and ggplot does the rest.
In your case, when you define L just do
L <- ifelse(Z==7, "Class A", ifelse(Z==7.5, "Class B", NA))

geom_textis another label adding option. Between the two there is a lot of extra options like moving the position of the label or customising the appearance of the label to suit your data

To stick with your base R plotting, you can use the text function.
Since you do not provide your FunctionZ I just use some example. I placed the labels to the left of the points. Depending on the shape of your function, you may wish to adjust the pos argument to place them elsewhere.
Z=seq(1,10,by=0.5)
functionZ = function(x) x + sin(x)
Pr=lapply(Z,functionZ)
plot(Z,Pr,main="CAT Bond Price with increasing attachment points",
xlab="Attachment Point",ylab="Price")
grid(nx = NULL, ny = NULL, col = "blue", lty = "dotted")
text(x=c(5,7.5), y=functionZ(c(5,7.5)), labels= c("Class A", "Class B"), pos=2)
