quick plot for a raster based on level_plot

FUNCTION_DESCRIPTION

plot_rast(in_rast, band = 1, in_poly = NULL, in_points = NULL,
  background = FALSE, limits = NULL, tails = c(0, 1),
  palette = "RdYlGn", legend_type = "standard",
  col_outlow = "gray10", col_outhigh = "gray90", maxpixels = 5e+05,
  title = "Raster Plot", plot_now = TRUE, ...)

Arguments

in_rast	Input raster object or file
band	PARAM_DESCRIPTION, Default: 1
in_poly	optional input polygon vector object or file to be overlayed on the plot, Default: NULL
in_points	optional input points vector object or file to be overlayed on the plot, Default: NULL
background	not used, Default: FALSE
limits	numeric array [2] optional limits governing the range of values to be plotted (e.g., c(0.2,0.4)), Default: NULL
tails	numeric array [2] percentiles used to "cut" the values to be plotted to allow a "good" representation. Values outside the specified percentiles will be plotted as NoData, or using the colors specified in col_outlow and col_outhigh, Default: c(0.02, 0.98) (meaning cutting the values at the 2nd and 98th percentile)
palette	Palette to be used for colors (see RColorBrewer::brewer.pal), Default: 'RdYlGn'
legend_type	"standard" or "custom" (see examples), Default: 'standard'
col_outlow	Color used to plot the values below the lower limit/tail. Can be a character corresponding to a valid "R" color or HEX representation, Default: 'gray10'
col_outhigh	Color used to plot the values below the lower limit/tail. Can be a character corresponding to a valid "R" color or HEX representation, Default: 'gray90'
maxpixels	numeric Maximum number of pixels to be plotted. Increase this to have better rendering at the cost of speed!, Default: 5e+05
title	character Title for the plot, Default: 'Raster Plot'
plot_now	logic If TRUE, the plot is immediately printed to screen. Otherwise, an object allowing later plotting/modifications is returned, Default: TRUE
...	Any other arguments (?)
