Add support for removing variable linear trend based on covariate (#23).
Adds support for converting long-form tables into matrices corresponding to two-dimensional spatial positions (#20).
The aggregation method for hierarchical clustering in
hclustgeo_disc() is set to ward.D2 by default
(#18).
Add hclustgeo_disc for hierarchical clustering with
spatial soft constraints (#13).
Add spade_psd for the fast estimation of the SPADE
model psd-value.
Add sf_gk_proj_cgcs2000() function.
geodetector_q for the fast estimation of the
geodetector q-value.check_tbl_na and tbl_all2int functions

packages.Fix the bug that causes R to crash when the input x
is a factor or character in the
discretize_vector function (#12).
Implement the formula_varname function to return the
corresponding variable names from both formula and
data.

ssh_test using Rcpp to enhance performance
(#5).
Introduce the discretize_vector function to support
variable discretization (#6).
Apply the loess_optnum function to select the
optimal number of discretization intervals (#10).
Implement spatial variance calculation in the spvar
function, with support for both R and C++
implementations (#11).
Rename dummy_vector to dummy_vec for
consistency in naming conventions.
Add the sf_coordinates function to extract
coordinates from sf objects.
Begin to use Rcpp to complete some tasks with high
computational complexity.

Inhibit the warning information produced by
spdep.
Add sf_utm_proj_wgs84() function.
sf_distance_matrix() function.Update the function documentation for
spdep_contiguity_swm() and
spdep_distance_swm().
Move the source code from SpatLyu/sdsfun on GitHub
