scat_cont_plot {BioPred}R Documentation

Scatter Plot for a Biomarker Associated with Continuous Outcome

Description

Generates a scatter plot for exploring the relationship between a continuous response variable and a biomarker variable.

Usage

scat_cont_plot(
  yvar,
  xvar,
  data,
  ybreaks = NULL,
  xbreaks = NULL,
  yvar.display = yvar,
  xvar.display = xvar
)

Arguments

yvar

Continuous response variable name.

xvar

biomarker name.

data

The dataset containing the variables.

ybreaks

Breaks on the y-axis.

xbreaks

Breaks on the x-axis.

yvar.display

Display name for the response variable.

xvar.display

Display name for the biomarker variable.

Value

A list containing correlation coefficients, scatter plot, slope, and intercept.

Examples

data <- data.frame(
  outcome = rnorm(100, mean = 10, sd = 2),
  biomarker = rnorm(100, mean = 0, sd = 1)
)

# Generate a scatter plot with default axis breaks
scat_cont_plot(
  yvar = "outcome",
  xvar = "biomarker",
  data = data,
  yvar.display = "Continuous Outcome",
  xvar.display = "Biomarker Level"
)

# Generate a scatter plot with specified axis breaks
scat_cont_plot(
  yvar = "outcome",
  xvar = "biomarker",
  data = data,
  ybreaks = seq(5, 15, by = 1),
  xbreaks = seq(-2, 2, by = 0.5),
  yvar.display = "Continuous Outcome",
  xvar.display = "Biomarker Level"
)
