arrayplot: Show an image based on row/column information

In january3/myfuncs: loads a few functions I often need

Description

Show an image based on row/column information

Usage

spatial.avg(mat, window = 20)

## S3 method for class 'arrayplot'
plot(x, ...)

arrayplot(rows, cols, vals, byrow = TRUE, n.row = max(rows),
  n.col = max(cols), pal = NULL, bg.col = "min")

Arguments

mat	an object of class arrayplot
window	window size to average
rows	integer vector with row positions
cols	integer vector with column positions
vals	numeric vector with values to plot
byrow	should the image be plotted row-wise (default:TRUE)
n.row	number of rows (if NULL, maximum value of rows)
pal	Character vector to use as color palette for the image
bg.col	how the missing values should be extrapolated

Details

The image matrix is created from three columns containing the value to plot and its position (row and column) on the image.

spatial.avg can be used to average the image.

Value

spatial.avg and arrayplot both return an object of class arrayplot.
