Plot covariate prevalence — plotCovariatePrevalence • CohortMethod

Plot prevalence of binary covariates in the target and comparator cohorts, before and after matching. Requires running computeCovariateBalance first.

plotCovariatePrevalence(
  balance,
  threshold = 0,
  title = "Covariate prevalence",
  fileName = NULL,
  beforeLabel = "Before matching",
  afterLabel = "After matching",
  targetLabel = "Target",
  comparatorLabel = "Comparator"
)

Arguments

balance: A data frame created by the computeCovariateBalance function.
threshold: A threshold value for standardized difference. When exceeding the threshold, covariates will be marked in a different color. If threshold = 0, no color coding will be used.
title: The main title for the plot.
fileName: Name of the file where the plot should be saved, for example 'plot.png'. See the function ggsave in the ggplot2 package for supported file formats.
beforeLabel: Label for the before matching / stratification panel.
afterLabel: Label for the after matching / stratification panel.
targetLabel: Label for the x-axis.
comparatorLabel: Label for the y-axis.

Value

A ggplot object. Use the ggplot2::ggsave function to save to file in a different format.
