Changes in version 0.3.1 (2025-11-07) - Bug fix - Avoid errors when detecting the number of available cores for parallel processing. Changes in version 0.3.0 (2023-09-23) - Major changes - uci() now accepts columns with NA values. In such cases, NAs are replaced with zero as they represent zero activities. - improved documentation - The package now uses Queen contiguity (spdep::poly2nb(geo, queen=TRUE)) to determine neighboring polygons whe considering spatial link distances. - Update vignette Changes in version 0.2.0 (2023-06-14) - Major changes - The uci function now has a new parameter dist_type that allows users to choose whether calculations should be based on "euclidean" distances (Default) or "spatial_link" distances. Spatial link distances consider Euclidean distances along the links of spatial neighbour links. In the case of areas with a concave shape (like a bay), it is strongly recommended to use "spatial_link" distances (even though they are computationally more costly) because simple Euclidean distances can bias UCI estimates in those cases. - The uci function now has a new parameter parallel that speeds up calculations for large areas comprised with many polygons. - Minor changes - Minor updates to documentation - Performance improvments Changes in version 0.1.0 (2023-06-11) - Initial CRAN release.
