PlotEquiMap: Maps A Two-Dimensional Variable On A Cylindrical Equidistant Projection

Description

Map a two dimensional matrix with (longitude, latitude) dimensions on a cylindrical equidistant latitude and longitude projection.

Usage

PlotEquiMap(var, lon, lat, toptitle = "", sizetit = 1, units = "", 
            brks = NULL, cols = NULL, square = TRUE, 
            filled.continents = TRUE, contours = NULL, brks2 = NULL, 
            dots = NULL, axelab = TRUE, labW = FALSE, intylat = 20, intxlon = 20, 
            drawleg = TRUE, boxlim = NULL, boxcol = 'purple2', boxlwd= 10,
            subsampleg = 1, numbfig = 1, colNA = "white")
