geom_hline
Package
ggplot2 (Wickham 2016 )
Description
Draw a horizontal line (\(Y=c\) ) for a given value of \(c\) , which is known as yintercept.
Understandable aesthetics
Unlike most other geoms, geom_hline does not depend on the x and y variables that we map for the main plot. geom_hline has its own independent characteristics: yintercept. The yintercept can be passed either as a arguments or aesthetic.

Example
a1 <- ggplot (worldbankdata, aes (y = Cooking, x= Electricity)) + geom_hline (yintercept = 50 ) +
labs (title= "a1: `geom_hline` only" ) +
theme (aspect.ratio = 1 )
a2 <- ggplot (worldbankdata, aes (y = Cooking, x= Electricity)) +
geom_point () +
geom_hline (yintercept = 50 ) +
labs (title= "a2: `geom_point + \n geom_hline` both" ) +

Understandable aesthetics
Unlike most other geoms, geom_hline does not depend on the x and y variables that we map for the main plot. geom_hline has its own independent characteristics: yintercept. The yintercept can be passed either as a arguments or aesthetic.
