Get annual averages of seagrass frequency occurrence by bay segments and year

Usage

anlz_transectave(
  transectocc,
  bay_segment = c("OTB", "HB", "MTB", "LTB", "BCB"),
  total = TRUE,
  yrrng = c(1998, 2024),
  rev = FALSE
)

Arguments

transectocc: data frame returned by anlz_transectocc
bay_segment: chr string for the bay segment, one to many of "OTB", "HB", "MTB", "LTB", "BCB"
total: logical indicating if average frequency occurrence is calculated for the entire bay across segments
yrrng: numeric indicating year ranges to evaluate
rev: logical if factor levels for bay segments are reversed

Value

A data frame of annual averages by bay segment

Details

The focat column returned in the results shows a color category based on arbitrary breaks of the frequency occurrence estimates (foest) at 25, 50, and 75 percent. These don't necessarily translate to any ecological breakpoints.

Examples

if (FALSE) { # \dontrun{
transect <- read_transect()
} # }
transectocc <- anlz_transectocc(transect)
