Plot background of multidimensional plots

This function creates a ggplot object with customized axes range (same for both), names and background

Usage

background.plot(range_faxes, faxes_nm, color_bg)

Arguments

range_faxes: a vector with minimum and maximum values of axes. Note that to have a fair representation of position of species in all plots, they should have the same range. Default: range_faxes = c(NA, NA) (the range is computed according to the range of values among all axes).
faxes_nm: a vector with axes labels for figure.
color_bg: a R color name or an hexadecimal code used to fill plot background. Default: color_bg = "grey95".

Value

A ggplot object plotting background of multidimensional graphs.

                               color_bg    = "grey90")
