plot_density: Plots a density or image
In sppmix: Modeling Spatial Poisson and Related Point Processes

Description Usage Arguments Details Author(s) See Also Examples

Create a 2d image or contour plot of the density, intensity or any image object.

For examples see

1 2	plot_density(density_df, contour = FALSE, grayscale = FALSE, pp = NULL, surf = NULL, ppsize = 1, main = "2d surface (density or intensity)")

`density_df`	A data frame. Typically density_df=as.data.frame(imdens), where imdens an `im` object.
`contour`	Logical flag requesting the countour plot only.
`grayscale`	Plot in gray scale. Default is FALSE (use colors).
`pp`	Optional point pattern to display (a `ppp` or `sppmix` object).
`surf`	Optional `intensity_surface` object containing means to be displayed in the plot.
`ppsize`	Size of the points in the plot.
`main`	A title for the 2d plot.

This function does not open a new window for the plot.
