In eva3dm: Evaluation of 3D Meteorological and Air Quality Models

Plot the difference from two SpatRaster objects

Description

Custom difference (x - y) plots for SpatRaster object (based on terra package)

Usage

plot_diff(
  x,
  y,
  col,
  absolute = TRUE,
  relative = TRUE,
  lim_a = NA,
  lim_r = NA,
  scale,
  unit = c(units(x), expression("%")),
  ...
)

Arguments

x	SpatVector points
y	values to plot
col	color
absolute	to plot absolute difference
relative	to plot relative difference
lim_a	range of values for absolute scale
lim_r	range of values for relative scale
scale	variable multiplier for absolute difference
unit	annotation for units
...	arguments to be passing to plot_raster

Value

No return value

Examples

folder <- system.file("extdata",package="eva3dm")
wrf    <- paste0(folder,"/wrfinput_d01")
A      <- wrf_rast(wrf,'XLAT')
terra::units(A) <- 'degrees'
B      <- wrf_rast(wrf,'XLONG')
plot_diff(A,B,int = 2)
