geom_hline_interactive: Horizontal interactive reference line

Description

The geometry is based on geom_hline. See the documentation for those functions for more details.

Usage

geom_hline_interactive(mapping = NULL, data = NULL, ..., yintercept,
  na.rm = FALSE, show.legend = NA)

Arguments

mapping

The aesthetic mapping, see geom_point.

data

A data frame, see geom_point.

yintercept

controls the position of the line

na.rm

See geom_point.

show.legend
