matchedwakeOverloads the default plot() for objects of class matchedwake. Returns a contour plot: The lighter the color the larger the estimated treatment effect. The corresponding standard errors are indicated by shading out some of the estimates: No shading corresponds to \(p<alpha1\) for the treatment effect in the diff-in-diffs analysis. Dotted lines indicate p-values between alpha1 and alpha2 and full lines indicate \(p>alpha2\). The cells indicating effect size and significance level are arranged in a table where each field corresponds to one specific combination of spatial and temporal sizes.
# S3 method for matchedwake
plot(x, zlim = NA, plotNAs = TRUE, ...)
object of class matchedwake.
Manually sets the range of the color map of the contour plot, required format is c(MINIMUM,MAXIMUM). Default = NA, i.e. the range is automatically set from the MINIMUM and MAXIMUM values of the estimates.
Boolean indicating whether or not to visualize NA estimates as ``no effect'' (i.e. 0). Default = TRUE.
