  overwrite = FALSE, outfile = asc$file, closedev = TRUE,
  pdfargs = NULL, add = FALSE, asp = 1, mar = c(0, 0, 0, 0),
  mgp = c(3, 0.7, 0), col = seqPal(100), bg = "grey", pch = 15,
  cex = 0.1, legend = TRUE, title = asc$name, legargs = NULL, ...)

Arguments

asc	List returned by read_asc or character string giving a filename (passed to read_asc). DEFAULT: file.choose()

mar, mgp	Plot margins and margin placement, see par. Margins are increased if missing and asc$proj != NA. DEFAULT: c(0,0,0,0), c(3,0.7,0)
col	Color palette. DEFAULT: berryFunctions::seqPal(100)
bg	Graph background color. DEFAULT: "grey"
pch, cex	Point type + size for colPoints if asc$proj != NA. DEFAULT: 15, 0.1
legend	Logical: add colPointsLegend? DEFAULT: TRUE
title	Character: Legend title. DEFAULT: asc$name (obtained from filename)
