Quick geographic plot of occurrence data — occurrences

Generates a plot of occurrence data retrieved using occurrences.The plot uses an Australian basemap and colours the occurrence records dots according to parameters

occurrences_plot(
  x,
  filename = "Rplots.pdf",
  qa = c("fatal", "error"),
  grouped = FALSE,
  taxon_level = "species",
  pch,
  cex = 0.75,
  ...
)

Arguments

x	list: a list object that has been downloaded using `occurrences`
filename	string: name of file to be created; defaults to RPlots.pdf
qa	string vector: list of record issues to be mapped; these can be assertion columnnames, or "all" or "none" or any combination of "error", "warning" or "fatal". Column or categories in your dataset can be viewed using `check_assertions`.
grouped	logical: TRUE creates a single plot for all observations; FALSE plots individual maps for the taxon level defined.
taxon_level	string: taxonomic level at which to create maps; possible values are "species", "genus", "family", or "order"
pch	single number or character representing point type. See description of `pch` in `points`.
cex	numeric: character (or symbol) expansion. See description of `cex` in `points`.
...	: other options passed to pdf()
