Description Usage Arguments Details Value Author(s) Examples

plot_extremes Plot floods and droughts episodes using the function find_flood_drought. This function employs the definition proposed by Mckee et al. (1993) using a time series of standardized precipitation values. A drought (flood) is defined as a period of time in which the SPI is continuously negative (positive) reaching at least one value lower (higher) or equal to -1 (1).

1	plot_extremes(data, threshold = 1)

`data`	A `mbsi` object returned by `spi` or `mbsi`, which contains the standardized precipitation values.
`threshold`	An numeric value used to detect the extreme events, 1 (-1) is used by default as proposed by Mckee et al. (1993).

Although the definition of Mckee et al. (1993) uses a threshold of 1 (-1). Other values can be used for this threshold.

A ggplot object. The graph is shown when this object is printed.
