displayPixels: Display the pixels and grandchildren

In rcosmo: Cosmic Microwave Background Data Analysis

Description

Display the pixels spix at resolution j by colouring in the grandchildren of spix at resolution plot.j

Usage

displayPixels(
  boundary.j,
  j,
  plot.j = 5,
  spix,
  boundary.col = "gray",
  boundary.lwd = 1,
  incl.labels = 1:(12 * 4^boundary.j),
  col = "blue",
  size = 3
)

Arguments

boundary.j	The resolution to display boundaries at. If this is missing then boundaries will not be plotted.
j	The resolution that spix are specified at.
plot.j	The resolution to plot grandchildren at
spix	Integer vector. The pixel indices to display. These must be in nested order.
boundary.col	The boundary colour.
boundary.lwd	The boundary line width.
incl.labels	Integer vector of pixel indices to label at resolution j.
col	The colour to make the grandchildren.
size	The size to make the grandchildren.

Examples

## Example 1

## Plot base pixels 1,2,3 by colouring their grandchildren at resolution
## 5 (by default). No pixel boundaries.
displayPixels(j=0, spix=c(1,2,3))

## Plot base pixels 1,2,3 display and their boundaries (boundary.j=0)
displayPixels(0,0, spix=c(1,2,3))

## Plot base pixels 1,2,3 by colouring their grandchildren at resolution 2
displayPixels(0,0, plot.j = 2, spix=c(1,2,3))

## Example 2

demoNeighbours <- function(p,j) {
  neighbours(p, j)
  displayPixels(boundary.j = j, j = j, plot.j = 5,
                spix = neighbours(p, j),
                boundary.col = "gray",
                boundary.lwd = 1,
                incl.labels = neighbours(p, j),
                col = "blue",
                size = 3)
  rcosmo::displayPixelBoundaries(nside = 1, col = "blue", lwd = 3)
}
