[R-sig-Geo] Selecting a range of values in a specific column for R ggplot

[Alexander Ilich]

Make sure to include the comma after the numbers so that you're selecting rows x through y and all columns. For example, GEV[17:21,] not GEV[17:21]

That you so much! Yes, this stopped the error from appearing.
>From what I see, though, when I attempt to change the subset from [1:4] to, say, [17:21] or [30:34], I end up with the exact same plots. Why could that be? The idea would be to make different curves on the same plot by changing the subset.

Hello,
try
newplot <- ggplot(data = GEV[1:4, ], aes(x = RL45)) + geom_density(color
= "midnightblue") + xlab("Location (mm/day") + ggtitle("Global Location
under RCP4.5") + xlim(300, 350)
HTH,
