Add lines with labels to pre-existing ggplot

Description

Add lines with labels to pre-existing ggplot

Usage

add_lines(
  p,
  df,
  xpos = 0.3,
  add.coord.fixed = TRUE,
  lty = NULL,
  color = NULL,
  size = 0.5,
  add_theme_bw2 = TRUE,
  ...
)

Arguments

p	An object of class ggplot
df	A data.frame. Required columns are slope, intercept and label
xpos	A numeric. Relative horizontal position
add.coord.fixed	Logical. Whether or not add coord_fixed() function
lty	line type
color	line color
size	line size
add_theme_bw2	logical Whether or not add theme_bw2()
...	Further arguments to be passed to geom_text

Examples

require(ggplot2)
fit=lm(mpg~wt*hp,data=mtcars)
df=calEquation(fit)
p=ggplot(data=mtcars,aes(x=wt,y=mpg))
add_lines(p,df)
add_lines(p,df,lty=1:3,color=1:3,size=1)
fit=lm(mpg~wt*vs,data=mtcars)
df=calEquation(fit)
p=ggplot(data=mtcars)+geom_point(aes(x=wt,y=mpg))
add_lines(p,df)
add_lines(p,df,lty=1:2,color=1:2,size=1)+theme_bw()
