levelplot2D {BSPBSS}

levelplot for 2D images.

Description

The function plots 2D images for a data matrix.

Usage

levelplot2D(
  S,
  coords,
  lim = c(min(S), max(S)),
  xlim = c(0, max(coords[, 1])),
  ylim = c(0, max(coords[, 2])),
  color = bluered(100),
  layout = c(1, nrow(S)),
  file = NULL
)

Arguments

S

Data matrix with q rows (sample) and p colums (pixel).

coords

Coordinates matrix with p rows (pixel) and 2 columns (dimension), specifying the coordinates of the data points.

lim

2-dimensional numeric vector, specifying the limits for the data.

xlim

2-dimensional numeric vector, specifying the lower and upper limits of x.

ylim

2-dimensional numeric vector, specifying the lower and upper limits of y.

color

Colorbar.

layout

2-dimensional numeric vector, specifying the number of rows and number of columns for the layout of components.

file

Name of the file to be saved.

Value

No return value.

Examples

sim = sim_2Dimage(length = 30, sigma = 5e-4, n = 30, smooth = 6)
levelplot2D(sim$S,lim = c(-0.04,0.04), sim$coords)
