Arguments

Name	Description
data	A dataframe of QTc dataset
fit	a lme model to make predictions with
conc_col	an unquoted column name of concentration measurements
dv_col	an unquoted column name of dQTC measurements
id_col	an unquoted column name of ID data, used when control predictors is provided to compute delta delta dv
ntime_col	an unquoted column name of Nominal time data, used when control predictors is provided to compute delta delta dv
trt_col	an unquoted column name of Treatment group data, used when control predictors is provided to compute delta delta dv
treatment_predictors	list of a values for contrast. CONC will update
control_predictors	list of b values for contrast
reference_threshold	optional vector of numbers to add as horizontal dashed lines
conf_int	confidence interval fraction, default = 0.9
nbins	number of bins for quantiles, or vector of cut points for computing average
error_bars	a string to denote which errorbars to show, CI, SE, SD or none.
contrast_method	a string specifying contrast method when using control_predictors: “matched” for individual ID+time matching (crossover studies), “group” for group-wise subtraction (parallel studies)
style	a named list of any argument that can be passed to style_plot

Returns

a plot
