GeoCovDisplay function

UTF-8

Image plot displaying the pattern of the sparsness of a covariance matrix.

GeoCovDisplay(covmatrix,limits=FALSE,pch=2)

Arguments

• covmatrix: An object of class GeoCovmatrix. See the Section Details .
• limits: Logical; If TRUE and the covariance matrix is spatiotemporal or spatial bivariate then vertical and horizontal lines are added to the image plot.
• pch: Type of symbols to use in the image plot.

Details

For a given covariance matrix object (GeoCovmatrix) the function diplays the pattern of the sparsness of a covariance matrix where the white color represents 0 entries and black color represents non zero entries

Returns

Produces a plot. No values are returned.

Examples

library(GeoModels)

  # Define the spatial-coordinates of the points:
x <- runif(100, 0, 2)
y <- runif(100, 0, 2)
coords=cbind(x,y)
matrix1 <- GeoCovmatrix(coordx=coords, corrmodel="GenWend", param=list(smooth=0,
                      power2=4,sill=1,scale=0.2,nugget=0))
