Plots unit by unit difference-in-differences. Dot size indicates the weights omega_i used in the average that yields our treatment effect estimate. This estimate and endpoints of a 95% CI are plotted as horizontal lines. Requires ggplot2

Arguments

estimates

as output by synthdid_estimate. Can be a single one or a list of them.

negligible.threshold

Unit weight threshold below which units are plotted as small, transparent xs instead of circles. Defaults to .001.

negligible.alpha

Determines transparency of those xs.

se.method

the method used to calculate standard errors for the CI. See vcov.synthdid_estimate. Defaults to 'jackknife' for speed. If 'none', don't plot a CI.

units

a list of control units --- elements of rownames(Y) --- to plot differences for. Defaults to NULL, meaning all of them.
