eda_add.Rd

eda_add adds graphical EDA elements to a scatter plot. Currently only adds eda_rline fit and points.

Usage

eda_add(
  x,
  pch = 24,
  p.col = "darkred",
  p.fill = "yellow",
  lty = 1,
  l.col = "darkred"
)

Arguments

x

Object of class eda_rline

pch

Point symbol type

p.col

Point color passed to col

p.fill

Point fill color passed to bg (Only used for pch ranging from 21-25)

lty

Line type

l.col

Line color

Value

Returns the eda_rline intercept and slope.

  • a: Intercept

  • b: Slope

Details

This function adds an eda_rline slope and 3-pt summary points to an existing scatter plot.


See the accompanying vignette Resistant Line for a detailed breakdown of the resistant line technique.

Examples


eda_lm(mtcars, x = wt, y = mpg)
#> (Intercept)           x 
#>   37.285126   -5.344472 
Mr <- eda_rline(mtcars, x=wt, y=mpg)
eda_add(Mr, l.col = "blue")

#> $a
#> [1] 37.61522
#> 
#> $b
#> [1] -5.504814
