Hi:

Since you didn't provide your data in a readable form for others, we had
to resort to other methods:

x <- rnorm(100, 180, 20)
y <- rnorm(100, 190, 15)
df <- data.frame(x = x, y = y)
plot(y ~ x, data = df, subset = y > 200)

My plot has y values strictly above 200. Is that what you wanted?

HTH,
Dennis
