elfchange {elfgen}

R Documentation

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

# We don't run this example by R CMD check, because it takes >10s

# Generate plot of percent richness change for various percent flow reductions
watershed.df <- elfdata(watershed.code = '0208020104', ichthy.localpath = tempdir())
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)
