Which.Max function

Question

N <- 300
N.2 <- 800
N.3 <- 600

change.y <- c(N, N.2, N.3)
use.y <- which.max(change.y)
graph.ylim <- use.y + 100

The output is [2], which is correct technically, but I want the output to say 800, not 2. Then, I want to plug in use.y as the y-lim here:

  coord_cartesian(xlim = c(0:300), ylim = c(150:900)) + 
  ...

Does anyone know how to do this? When I plug in ylim = c(150:graph.ylim)) , my graph disappears.

Answer 1

> change.y
[1] 300 800 600
> use.y <- max(change.y)
> use.y
[1] 800
