Love Plot: Balance Diagnostics for Both Pathways

Description

Produces a publication-ready love plot showing standardised mean differences (SMDs) before and after IPW weighting for both the treatment and mediator pathways — stacked vertically in a single panel. This dual-pathway display is unique to RobustMediate; no other mediation package provides it.

Usage

plot_balance(x, threshold = 0.1, pathways = c("treatment", "mediator"), ...)

Arguments

x	A robmedfit object.
threshold	Absolute SMD threshold displayed as dashed reference lines. Reviewers conventionally accept |SMD| < 0.10. Default 0.1.
pathways	Character vector indicating which pathways to show. Options: "treatment", "mediator", or both (default).
...	Ignored (for S3 consistency).

Value

A ggplot2 object. Add layers or themes as usual.

Examples

fit <- robustmediate(
  treatment_formula = X ~ Z1 + Z2 + Z3,
  mediator_formula  = M ~ X + Z1 + Z2 + Z3,
  outcome_formula   = Y ~ X + M + Z1 + Z2 + Z3,
  data = sim_mediation, R = 50
)
plot_balance(fit)
plot_balance(fit, threshold = 0.05, pathways = "treatment")
