Description

produces multi-resolution network.

Usage

 `1` ```network.design(latlon, method = "Oh", type = "reduce", nlevel, x) ```

Arguments

 `latlon` grid points of observation sites in degree `method` network design method, "cover", "ModifyGottlemann", "Gottlemann" or "Oh" `type` specifies grid type, "regular" or "reduced" `nlevel` the number of observations in each resolution when using the method ‘"cover"’ `x` radius in degree

Details

This function partitions the grid points of observations into networks. Each network corresponds resolution level and level 1 is the most detailed level. Possible methods are

‘"cover"’ for utilizing ‘"cover.design"’ in the package ‘"field"’

‘"ModifyGottlemann"’ for modified G\"ottlemann's method

‘"Gottlemann"’ for G\"ottlemann's method

‘"Oh"’ for Oh's method.

For ‘"ModifyGottlemann"’, ‘"Gottlemann"’ and ‘"Oh"’, two types of design, ‘"regular"’ and ‘"reduced"’ are provided.

Value

 `netlab` vector of network labels indicating level of multi-resolution.
