Isobands via matix and extent

Description

This is purely a re-orientation of isoband it self, rather than having to construct a degenerate rectilinear data set, we just provide a matrix and optionally an extent. The extent scaling can be done independently if wanted.

Usage

xisobands(x, extent = NULL, lo = NULL, hi = NULL, nlevs = 12L)

Arguments

x	matrix of numeric
extent	xmin,xmax,ymin,ymax georeference of the x matrix
lo	low levels
hi	high levels
nlevs	number of levels in the case that neither hi nor lo provided

Details

Matrix orientation is 'raster', i.e. like rasterImage() and not like image() which is isoband is expecting.

Values for lor and/or hi may be provided or left out. If both are left out can use nlevs to get a quantile set of levels from the data.

Value

and isobands, iso object

Examples

xisobands(diag(10))
