Draw Horizontal/Vertical Lines

Description

Draws horizontal or vertical lines on an existing figure.

Usage

hv_line(h = NULL, v = NULL, l = NULL, ...)

Arguments

h	A vector with the y-axis positions for horizontal lines.
v	A vector with the x-axis positions for vertical lines.
l	The lower and upper coordinates to determine the length of the line (if y is not NULL, l is taken as the x-axis coordinates; if x is not NULL, l is taken as the y-axis coordinates).
...	Additional arguments to be passed to the segments function.

Examples

# Create a blank plot
blank_plot()

# Draw horizontal line
hv_line(h = .5, lty = 2)
# Draw vertical line
hv_line(v = .5, lwd = 2)

# Control width of horizontal line
hv_line(h = .25, l = c(.25, .75), col = "blue")
# Control height of vertical line
hv_line(v = .25, l = c(.25, .75), col = "orange")
