In malaria-atlas-project/malariaAtlas: An R Interface to Open-Access Malaria Data, Hosted by the 'Malaria Atlas Project'

Quickly visualise Rasters downloaded from MAP

Description

autoplot.SpatRaster creates a map of all rasters in a SpatRaster object and displays these in a grid.

Usage

## S3 method for class 'SpatRaster'
autoplot(
  object,
  ...,
  shp_df = NULL,
  legend_title = "",
  plot_titles = TRUE,
  fill_scale_transform = "identity",
  fill_colour_palette = "RdYlBu",
  printed = TRUE
)

Arguments

object	SpatRaster object to be visualised.
...	Other arguments passed to specific methods
shp_df	Shapefile(s) (data.frame) to plot with downloaded raster.
legend_title	String used as title for all colour scale legends.
plot_titles	Plot name of raster object as header for each individual raster plot?
fill_scale_transform	String givning a transformation for the fill aesthetic. See the trans argument in continuous_scale for possible values.
fill_colour_palette	String referring to a colorbrewer palette to be used for raster colour scale.
printed	Logical vector indicating whether to print maps of supplied rasters.

Value

autoplot.SpatRaster returns a list of plots (gg objects) for each supplied raster.

Examples

## Not run: 
# Download PfPR2-10 Raster (Bhatt et al 2015) and raw survey points
#   for Madagascar in 2013 and visualise these together on a map.

# Download madagascar shapefile to use for raster download.
MDG_shp <- getShp(ISO = "MDG", admin_level = "admin0")

# Download PfPR2-10 Raster for 2013 & plot this
MDG_PfPR2_10 <- getRaster(surface = "Plasmodium falciparum PR2-10", 
                          shp = MDG_shp, year = 2013)
p <- autoplot(MDG_PfPR2_10, shp_df = MDG_shp)

# Download raw PfPR survey points & plot these over the top of the raster
pr <- getPR(country = c("Madagascar"), species = "Pf")
# p[[1]] + geom_point(data = pr[pr$year_start==2013,],
#            aes(longitude, latitude, fill = positive / examined,
#                size = examined), shape = 21) +
#   scale_size_continuous(name = "Survey Size") +
#    scale_fill_distiller(name = "PfPR", palette = "RdYlBu") +
#    ggtitle("Raw PfPR Survey points\n +
#          Modelled PfPR 2-10 in Madagascar in 2013")


# Download global raster of G6PD deficiency (Howes et al 2012) and visualise this on a map.
G6PDd_global <- getRaster(surface = "G6PD Deficiency Allele Frequency")
autoplot(G6PDd_global)
