panel.filledcontour: create smooth contour fills for lattice levelplots

In environmentalinformatics-marburg/Rsenal: Magic R Functions for Things Various

create smooth contour fills for lattice levelplots

Description

this panel function will create a smooth fill for a levelplot similar to filled.contour

Usage

panel.filledcontour(
  x,
  y,
  z,
  subscripts,
  fill.contours = TRUE,
  at,
  contours = TRUE,
  at.contours = NULL,
  col.regions = cm.colors,
  col = col.regions(length(at) - 1),
  col.contours = "black",
  lty.contours = 1,
  lwd.contours = 1,
  draw.labels = TRUE,
  ...
)

Arguments

x	vector
y	vector
z	vector
subscripts	optional
fill.contours	should regions between contours be (colour) filled?
at	sequence for the fill contours
contours	should contour lines be drawn?
at.contours	sequence for the contour lines
col.regions	colour palette for filling
col	set of colours passed on to filled.contour
col.contours	colour of contour lines
lty.contours	linetype of contour lines
lwd.contours	size of contours
draw.labels	should labels be drawn along the contour lines?
...	currently not used
