Semivariance values for a given spatio-temporal variogram model
Generates a surface of semivariance values given a spatio-temporal variogram model (one of separable, productSum, sumMetric, simpleSumMetric or metric)
variogramSurface(model, dist_grid, covariance = FALSE)
model |
A spatio-temporal variogram model generated through |
dist_grid |
A data.frame with two columns: |
covariance |
Whether the covariance should be computed instead of the variogram (default: FALSE). |
A data.frame with columns spacelag, timelag and gamma.
