In elfgen: Ecological Limit Function Model Generation and Analysis Toolkit

Plot percent richness change for various percent flow reductions

Description

Calculates and plots percent richness change resulting from streamflow reductions

Usage

elfchange(stats, yaxis_thresh, xlabel = FALSE, ylabel = FALSE)

Arguments

stats	A dataframe of ELF statistics
yaxis_thresh	Value used for specifying y-axis max limit
xlabel	Used to overwrite default x-axis label
ylabel	Used to overwrite default y-axis label

Value

Plot of percent decreases in richness from flow reductions

Examples

#elfdata(watershed.code = '0208020104', ichthy.localpath = tempdir(), use_cache = FALSE)
breakpt <- 500
elf <- elfgen(
   "watershed.df" = watershed.df,
   "quantile" = 0.95,
   "breakpt" = breakpt,
   "xlabel" = "Mean Annual Flow (ft3/s)",
   "ylabel" = "Fish Species Richness"
   )
elfchange(elf$stats, "yaxis_thresh" = 25)
