smooth plotting function

Description

Takes a data table of the form .(Lon,Lat,value) or .(Lat,Lon,value) and plots values on the globe after applying a kernel smoothing

Usage

plot_smooth(
  dt_plot,
  var = colnames(dt)[3],
  mn = var,
  rr = NULL,
  theta = 0.5,
  pixels = 256,
  col_scheme = "bwr",
  set_white = NULL,
  xlab = "Lon",
  ylab = "Lat",
  save_pdf = FALSE,
  save_dir = "./figures/",
  file_name = "diag_plot",
  stretch_par = NULL,
  exclude_land = FALSE,
  exclude_ocean = FALSE,
  legend = TRUE
)

Arguments

var	Character string. The name of the column containing the values for the plot. Default is the name of the third column of dt, to be used for subset data tables of the form .(Lon,Lat,var).
mn, rr	Title and range of the plot.
theta	parameter for the Gaussian smoothing kernel
pixels	Resolution of the plot
col_scheme	Either "bwr" for blue - white - red, "wr" for white - red, or "wb" for white - blue. Specifies the color scheme of the plot.
set_white	Forces the blue-white-red color scheme to center white at the set value if specified.
xlab, ylab	Labeling.
save_pdf, save_dir, file_name	Whether, where and under which name the plot should be saved.
stretch_par	Numeric. Only used when save_pdf == TRUE. Stretches the pdf output. Default is NULL, where it is stretched to #Lons/#Lats.
exclude_land	Should pixels on land be grayed out?
exclude_ocean	Should pixels on ocean be grayed out?
legend	Should the plot have a legend?
dt	The data table.

Value
