  alpha = 255,
  bgalpha = 0,
  colNA = NA,
  axes = FALSE,
  xlab = "",
  ylab = "",
  add = FALSE,
  zmax = NULL
)

Arguments

x	RasterLayer a RasterLayer to plot.
zlim	numeric a vector of length 2. Range of values to plot.

palette	string not well implemented.
reverse	boolean not well implemented.
alpha	integer transparency factor between 0 (transparent) and 255 (opaque).
bgalpha	integer transparency factor for NA values between 0 (transparent) and 255 (opaque).
colNA	string color for the background (i.e. NA values).
axes	boolean If TRUE, axes are added.
xlab	string x-axis label.
ylab	string y-axis label.
