Usage

construct_prob_plot(vals)
Arguments
vals
A numeric vector of annual peak discharge values obtained from
the readNWISpeak function of the dataRetrieval package.
Details
The Weibull plotting method is commonly used in flood-frequency analysis.
The basic procedure invovles ranking the values from highest to lowest and
calculating an exceedence probability (p = rank / (n + 1)) where n
is the total number of observations. The median annual flood (Q2) is the
flow with a probability of 0.5.
