[R] variable in annotation, ggplot2

[Troels Ring]

Hi friends - I have a simple problem of inserting values in label of a
ggplot2. I have a vector V with two values and want to show them in the
plot.

Here is what I tried -  at most get the first entry "28".

R version 3.6.1 (2019-07-05)

Windows 10

library(ggplot2)

x <- 1:5

y <- x^2

V <- c(28,14)

df <- data.frame(x=x,y=y)

ggplot(df,aes(x=x,y=y))+geom_line()+

    annotate("text",x=3,y=20,label=bquote(V ==.(as.vector(V))))

 

 

 

ggplot(df,aes(x=x,y=y))+geom_line()+

    annotate("text",x=3,y=20,label=expression(paste("V is ",V)))

 

 

ggplot(df,aes(x=x,y=y))+geom_line()+

    annotate("text",x=3,y=20,label=bquote(V ==.(V)))
