  data,
  fit,
  xdata_col,
  dv_col,
  conf_int = 0.9,
  nruns = 500,
  nbins = 10,

)

Arguments

data: A data frame containing C-QT analysis dataset
fit: An nlme::lme model object from model fitting
xdata_col: An unquoted column name for independent variable
dv_col: An unquoted column name for dependent variable
conf_int: Numeric confidence interval level (default: 0.9)
nruns: Integer number of simulations to run
nbins: Integer number of bins to break independent variable into - OR - a user specified vector for non-uniform binning
type: Integer for type parameter of stats::quantile
style: A named list of arguments passed to style_plot()

Value

a plot of the VPC results
