Plot SMD covariate balance

Renders a horizontal dot-plot of absolute standardized mean differences (|SMD|) for each covariate. Vertical reference lines at 0.10 (and optionally 0.20) mark conventional balance thresholds. Points are colored by whether |SMD| < 0.10.

Usage

plot_smd_balance(
  x,
  ref_010 = TRUE,
  ref_020 = FALSE,
  main = NULL,
  subtitle = NULL,
  palette = NULL,
  theme = c("clean", "minimal")
)

Arguments

x

A "smd_balance_table" object from smd_balance_table.

ref_010

Logical; draw a dashed reference line at |SMD| = 0.10. Default TRUE.

ref_020

Logical; draw a dotted reference line at |SMD| = 0.20. Default FALSE.

main

Character; plot title. Default "SMD Covariate Balance".

subtitle

Character; plot subtitle.

palette

Named list for color overrides: imbalanced, balanced, unclassified.

theme

Character; "clean" (default) or "minimal".

Value

A ggplot object.
