Contour plot(s) of a fitted linear model in ggplot2

Usage

gg_rsm(
  rsm_model,
  formula,
  decode = FALSE,
  n_columns = 2,
  text_size = 3,
  bins = 6,
  ...
)

rsm_model: Model of class "rsm"
formula: A formula, or a list of formulas
decode: This has an effect only if x is an rsm object or other model object that supports coded.data. In such cases, if decode is TRUE, the coordinate axes are transformed to their decoded values.
n_columns: number of columns for grid layout. Default is 2
text_size: size of text for labelled contour lines. Default is 3
bins: Number of contour bins. Overridden by binwidth
...: Other arguments passed on to contour(). For help with more arguments see ?rsm::contour.lm
