Plot covariate prevalence

Source: R/Balance.R
plotCovariatePrevalence.Rd

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

Usage

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.
