add_regime_shift_highlight: Highlight specific time spans
In ha0ye/portalDS: Compute Dynamic Stability for Rodents at Portal

Description Usage Arguments Details Value

Add transparent vertical slices, with boundaries specified by the lower_date and upper_date arguments.

add_regime_shift_highlight(my_plot, lower_date = as.Date(c("1983-11-12",
  "1990-01-06", "1998-12-22", "2009-05-23")),
  upper_date = as.Date(c("1985-03-16", "1992-04-04", "1999-11-06",
  "2011-01-05")), alpha = 0.5, fill = "grey30")

`my_plot`	the original ggplot object
`lower_date`	a vector of the beginnings of the time spans
`upper_date`	a vector of the ends of the time spans
`alpha`	the transparency of the bars to add to the plot
`fill`	the fill color of the bars to add to the plot

The default values for the time spans correspond to the 0.90 credibility intervals estimated from https://weecology.github.io/LDATS/paper-comparison.html. An alternative default are the values from Christensen et al. 2018: lower_date = as.Date(c("1983-12-01", "1988-10-01", "1998-09-01", "2009-06-01")) upper_date = as.Date(c("1984-07-01", "1996-01-01", "1999-12-01", "2010-09-01"))
