eda_scatter_with_regressions

Description

plots scatter plot with with linear and loess regressions. Can be used to check for linearity.

Usage

eda_scatter_with_regressions(
  data,
  ydata_col,
  xdata_col,
  trt_col = NULL,
  reference_threshold = NULL,
  loess_line = TRUE,
  linear_line = TRUE,
  span = 0.99,
  conf_int = 0.9,
  style = list(
)
)

Arguments

Name	Description
`data`	a dataframe of QT dataset
`ydata_col`	an unquoted column name of dependent variable measurements
`xdata_col`	an unquoted column name of independent variable measurements
`trt_col`	Optional - an unquoted column name of treatment group
`reference_threshold`	optional vector of numbers to add as horizontal dashed lines
`loess_line`	a bool to add LOESS regression line
`linear_line`	a bool to add a linear regression line
`span`	a fractional value for LOESS span parameter in geom_smooth if LOESS is used, default 0.99
`conf_int`	a fractional numeric for setting confidence interval, default = 9
`style`	a named list of any argument that can be passed to style_plot. Shapes are mapped to treatment groups and can be controlled via the shapes parameter in style

Returns

a plot
