Function to plot contours on spherical grid

Description

Function to plot contours on spherical grid

Usage

spherical_contour(
  field,
  FUN = "mean",
  lonR = NULL,
  latR = NULL,
  nx = 100,
  ny = 100,
  breaks = NULL,
  zlim = NULL,
  nlevels = 5,
  xlab = NULL,
  ylab = NULL,
  main = NULL,
  add = FALSE,
  col = "grey70",
  drawlabels = TRUE,
  verbose = FALSE
)

Arguments

field	A field object or a matrix with longitude and latitude attributes which is the output of esd::map.field
lonR	Center longitude of viewing angle
latR	Center latitude of viewing angle
nx	Length of output grid along x-direction. Default: nx=100
ny	Length of output grid along y-direction. Default: ny=100
breaks	Contour levels. If the argument 'breaks' is not defined, breaks = pretty(zlim, n=nlevels)
zlim	Range of contours. If the arguments 'breaks' and 'zlim' are not defined, zlim = range(field, na.rm=TRUE)
nlevels	Number of contour levels. If the arguments 'breaks' and 'nlevels' are not defined, nlevels=5
xlab	x-axis label
ylab	y-axis label
main	main title
add	a boolean; If TRUE, add contour lines to an existing plot. If FALSE, create new plot with contour lines
verbose	a boolean; if TRUE print information about progress
lat	A numeric vector of latitudes
