Create a scatterplot of the covariate balance — plotCovariateBalanceScatterPlot • CohortMethod

Create a scatterplot of the covariate balance, showing all variables with balance before and after matching on the x and y axis respectively. Requires running computeCovariateBalance first.

plotCovariateBalanceScatterPlot(
  balance,
  absolute = TRUE,
  threshold = 0,
  title = "Standardized difference of mean",
  fileName = NULL,
  beforeLabel = "Before matching",
  afterLabel = "After matching",
  showCovariateCountLabel = FALSE,
  showMaxLabel = FALSE
)

Arguments

balance: A data frame created by the computeCovariateBalance function.
absolute: Should the absolute value of the difference be used?
threshold: Show a threshold value for after matching standardized difference.
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 x-axis.
afterLabel: Label for the y-axis.
showCovariateCountLabel: Show a label with the number of covariates included in the plot?
showMaxLabel: Show a label with the maximum absolute standardized difference after matching/stratification?

Value

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