susie_plot_changepoint.Rd
Plots original data, y, overlaid with line showing susie fitted value and shaded rectangles showing credible sets for changepoint locations.

)
A susie fit generated by
susie_trendfilter(y,order = 0)
.
An n-vector of observations that are ordered in time or space (assumed equally-spaced).
Color for the line showing fitted values.
Size of the lines showing fitted values
Color of the shaded rectangles showing credible sets.
A ggplot2 plot object.
