Density plot in 2d using the grid package

density_2d_grid(
  zargs,
  ngrids = 25,
  ccol = NULL,
  clwd = 1,
  clty = 1,
  box = FALSE,
  box.width = 1,
  box.height = 1,
  group... = list(cex = 0.66),
  draw = FALSE,
  ...
)

Arguments

zargs

argument list as passed from zenplot()

ngrids

number of grid points in each direction. Can be scalar or a length-2 integer vector.

ccol

vector (which is then recycled to the appropriate length) giving the color of the contours

clwd

vector (which is then recycled to the appropriate length) giving the line widths of the contours

clty

vector (which is then recycled to the appropriate length) giving the line types of the contours

box

logical indicating whether a box should be drawn

box.width

width of the box

box.height

height of the box

group...

list of arguments passed to group_2d_grid (or NULL)

draw

logical indicating whether drawing should take place

...

additional arguments passed to gpar()

Value

grob (invisibly)

Note

- We use names depending on the 'type' here since otherwise, if one calls it once for 'p' and once for 'l', only one of them is plotted - The default point size was chosen to match the default of graphics
