uci()
now accepts columns with NA
values.
In such cases, NA
s are replaced with zero as they represent
zero activities.spdep::poly2nb(geo, queen=TRUE)
) to determine neighboring
polygons whe considering spatial link distances.Major changes
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.uci
function now has a new parameter
parallel
that speeds up calculations for large areas
comprised with many polygons.Minor changes
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
