[R] How to only show two numbers on bar_plot with ggplot

[Rui Barradas]

Hello,

Why not remove aes(x = ESRD,...) from the call to geom_bar and instead do

ed <- ggplot(e, aes(x = factor(ESRD)) + etc?


If you are using an aesthetic throughout the plot, put it in the call to 
ggplot().

Hope this helps,

Rui Barradas
