Plot eda_rline model — plot.eda

plot.eda_rline A plot method for lists of eda_rline class.

Usage

# S3 method for eda_rline
plot(
  x,
  type = "model",
  xlab = NULL,
  ylab = NULL,
  grey = 0.7,
  pch = 21,
  equal = TRUE,
  p.col = "grey50",
  p.fill = "grey80",
  size = 0.8,
  alpha = 0.7,
  model = TRUE,
  pt3 = TRUE,
  fit = TRUE,
  ...
)

Arguments

x: Object of class eda_rline.
type: Plot type. One of two: "model", "residuals".
xlab: Custom x-axis label. Defaults to column name.
ylab: Custom y-axis label. Defaults to column name.
grey: Grey level to apply to plot elements (0 to 1 with 1 = black).
pch: Point symbol type.
equal: Boolean determining if axes lengths should match (i.e. square plot).
p.col: Color for point symbol.
p.fill: Point fill color passed to bg (Only used for pch ranging from 21-25).
size: Point size (0-1).
alpha: Point transparency (0 = transparent, 1 = opaque). Only applicable if rgb() is not used to define point colors.
model: Boolean indicating if the resulting model should be added above plot. Only applies to type = "model".
pt3: Boolean indicating if the 3-pt summaries should be added to the plot. Only applies to type = "model".
fit: Boolean indicating if the fitted line should be added to the plot.
...: Arguments to be passed to subsequent methods.

Value

Does not return a value.

Details

The function generates a scatter plot with the fitted model from an eda_rline object.

Examples

r.lm    <- eda_rline(age_height, Months, Height)

plot(r.lm)

plot(r.lm, pt3 = FALSE)

plot(r.lm, type = "residuals")
