ausplots_visual {ausplotsR}R Documentation

Graphical illustration of sample TERN AusPlots data


Generates a set of graphical displays representing TERN AusPlots data based on geographic locations and vegetation attributes from the plot-based point intercepts (as generated by get_ausplots and other pre-processing functions).


ausplots_visual(my.ausplots.object = NULL, map = TRUE, map.attribute = TRUE, 
fraction.pie = TRUE, growthform.pie = TRUE, cumulative.cover = TRUE, 
whittaker = TRUE, outfile=NULL, max.plots = 5)




Optional (but required for map_ausplots) input raw data object as generated in a call from the get_ausplots function. The default graphical outputs require $ (for locations) and $veg.PI (for vegetation attributes) to be included in the AusPlots data extract.


Logical, whether to include a basic map of site locations in the context of Australia.


Logical, whether to include a map depicting site locations in Australia coded by cover of trees over 5 m high.


Logical, whether to include pie charts depicting fractional_cover.


Logical, whether to include pie charts depicting relative cover of plant growth forms.


Logical, whether to include graphs of cumulative cover estimates by species as point intercepts are taken across each AusPlot.


Logical, whether to include Whittaker plots depicting species abundance distributions.


Optional file path and name to which the output pdf file is written.


Maximum number of sites for which to display individual graphics panels. By default, max.plots sites are selected randomly. If you provide existing AusPlots data, max.plots sites are processed (in order) whenever fractional.pie or cumulative.cover are selected, because those calculations can be slow across a large number of plots.


By default, extracts sample data, allowing the user to explore the dataset in a single call, or to easily visualise an extracted AusPlots dataset. Included in the default demonstration plots are maps of plot locations with and without coding by tree cover, and then a set of four panels for a smaller sample of AusPlots, depicting data from the main vegetation tables in the package, i.e., fractional cover, growth form cover, species cover and species relative abundance. This function is intended as a simple demonstration of the data available. Refer to TERN tutorials for many other ways to visualise and explore AusPlots.


Plots are written to a pdf file to ensure consistent formatting, saved by default in the working directory.
