ggdid(
  object,
  ylim = NULL,
  xlab = NULL,
  ylab = NULL,
  title = "Group",
  xgap = 1,
  ncol = 1,
  legend = TRUE,
  group = NULL,
  ref_line = 0,
  theming = TRUE,
  grtitle = "Group",
  ...
)

Arguments

object

either a MP object or AGGTEobj object. See help(ggdid.MP) and help(ggdid.AGGTEobj).

ylim

optional y limits for the plot; setting here makes the y limits the same across different plots

xlab

optional x-axis label

ylab

optional y-axis label

title

optional plot title

xgap

optional gap between the labels on the x-axis. For example, xgap=3 indicates that the labels should show up for every third value on the x-axis. The default is 1.

ncol

The number of columns to include in the resulting plot. The default is 1.

legend

Whether or not to include a legend (which will indicate color of pre- and post-treatment estimates). Default is TRUE.

group

Vector for which groups to include in the plots of ATT(g,t). Default is NULL, and, in this case, plots for all groups will be included (ggdid.MP only).

ref_line

A reference line at this value, usually to compare confidence intervals to 0. Set to NULL to omit.

theming

Set to FALSE to skip all theming so you can do it yourself.

grtitle

Title to append before each group name (ggdid.MP only).
