rasterplot: Pretty plot of raster object

In MoisesExpositoAlonso/moiR: A set of R functions for an easy life and analyses

Description

Pretty plot of raster object

Usage

rasterplot(raster, objectname = deparse(substitute(raster)), name = "",
  rangecol = c(min(values(raster), na.rm = T), max(values(raster), na.rm =
  T)), midpoint = NULL, dimcol = 50, numbreak = 10, colbreaks = if
  (is.null(midpoint)) {     pretty(rangecol, dimcol) } else {    
  c(pretty(c(rangecol[1], midpoint), n = round(dimcol/2) - 1), midpoint,
  pretty(c(midpoint, rangecol[2]), n = round(dimcol/2) - 1)) } %>% unique(),
  legmid = NULL, legbreaks = if (is.null(legmid)) {     pretty(rangecol, n =
  numbreak - 1) } else {     c(pretty(c(rangecol[1], legmid), n =
  round(numbreak/2)), legmid, pretty(c(legmid, rangecol[2]), n =
  round(numbreak/2))) } %>% unique(), vecol = c("cyan", "dodgerblue1",
  "blue", "forestgreen", "orange", "red", "purple"), contrast = 0, pdf = F,
  add = F, plotlegend = T, discrete = F)

Arguments

raster	A raster layer object
objectname	The name of the object plotted or other name to keep track of the pdf
name	Title fo the plot
rangecol	Range of the color palette
dimcol	Number of color breaks in the gradient
numbreak	Number of breaks in the color scale
vecol	Color vector for the palette
contrast	Interger for number of increase contrast iteration
pdf	Logical whether to output plot as pedf
add	Logical whether this plot will be overplotted on an existing one in the graphic device
plotlegend	Logical whether the color legend is plotted. Useful when overlaying two maps.
breaks	Breaks used in the color scale

Value

Prints a plot of a raster object with a nice color palette and without axis (easily changed). If desired, it is outputed as pdf'.
