Show matrix of seagrass frequency occurrence by bay segments and year
data frame returned by
chr string for the bay segment, one to many of "HB", "OTB", "MTB", "LTB", "TCB", "MR", "BCB"
logical indicating if average frequency occurrence is calculated for the entire bay across segments
logical indicating if a neutral and continuous color scheme is used
numeric indicating year ranges to evaluate
numeric indicating alpha value for score category colors
numeric for size of text in the plot
optional chr string indicating font family for text labels
logical if factor levels for bay segments are reversed
chr string of location for bay segment labels, default on top, passed to
logical if matrix is created using plotly
numeric for width of the plot in pixels, only applies of
plotly = TRUE
numeric for height of the plot in pixels, only applies of
plotly = TRUE
Results are based on averages across species by date and transect in each bay segment
The color scheme is based on arbitrary breaks at 25, 50, and 75 percent frequency occurrence. These don't necessarily translate to any ecological breakpoints. Use
neutral = TRUE to use a neutral and continuous color palette.
