In RS-eco/ggmap2: R package to easily create nice maps

Create map(s) of one raster layer or a raster stack

Description

Read a global raster layer or raster stack and plot on a map

Usage

ggmap2(
  data,
  name = "",
  split = FALSE,
  trans = "identity",
  facet_grid = FALSE,
  crop = TRUE,
  grid = FALSE,
  colours = colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan", "#7FFF7F", "yellow",
    "#FF7F00", "red", "#7F0000"))(255),
  varnames = NA,
  subnames = "",
  outline = NA,
  extent = NA,
  ncol = 2,
  long = FALSE,
  country = TRUE,
  save = FALSE,
  filename = "Rplots.pdf"
)

Arguments

data	raster layer, raster stack or dataframe
name	character, name of legend
split	logical, should multiple plots have individual legends or not
trans	transform data
facet_grid	logical, default to FALSE, if TRUE facet_grid is used for plotting
crop	logical, default to TRUE, not implemented right now
grid	logical, default to FALSE, if TRUE a grid is added to the plot
colours	specify colourPalette used for ggplot2::scale_fill_gradientn()
varnames	character vector with names of data
subnames	character vector with subnames of data
outline	default is NA
extent	defaults to NA
ncol	specify number of columns for plotting with facet_wrap or ..., not needed if facet_grid is TRUE.
long	defaults to FALSE. Specify if data is in long format or not.
country	defaults to TRUE. Add country outline to plot.
save	defaults to FALSE. Specify if plot should be written to file.
filename	If save=TRUE you can specify the filename of your plot here

Value

ggplot2 object

Examples

# Load raster library
library(raster)
# Create data
r <- raster(nrow=90, ncol=180)
r <- setValues(r, rnorm(ncell(r), 0, 1))
#Create plots
ggmap2(r, name="Single", split=FALSE, ncol=1)
ggmap2(r, name="Single", split=FALSE, ncol=1, extent=c(-20, 70, -50, 80))
