lctools 0.3-0

Resubmission to CRAN after the package was archived on 2025-11-28.

CRAN compliance

• DESCRIPTION: added the Authors@R field, as now required by CRAN.
• Documentation: added package anchors to all Rd \link{} targets pointing to other packages, e.g. \link[pscl]{zeroinfl} (fixes the CRAN check NOTE/WARNING “Rd targets missing package anchors”).
• Data: GR.Municipalities.RData and VotesGR.RData are now saved with xz compression (removes the “significantly better compression” check WARNING and reduces the source tarball by about 0.9 Mb).
• DESCRIPTION: relaxed the R dependency to R (>= 3.5.0); the package uses no features specific to more recent R versions (the data files require the serialization format of R >= 3.5.0).

Documentation and vignettes

• Corrected spelling mistakes in the help pages (string, using, excludes, separate, respectively) and removed a mismatched reference URL in lcorrel.Rd.
• Vignettes are now built as HTML (rmarkdown::html_vignette) instead of PDF, removing the LaTeX build requirement and reducing package size.
• Vignettes: removed an obsolete reference to the retired ‘rgdal’ package, fixed typos, function-name casing (moransI, moransI.w) and an outdated thesis URL.

Code and tests

• random.test.data(): replaced 1:vars.no-1 with seq_len(vars.no - 1) in the covariate loop. The old code relied on a silent no-op for the zero index; behaviour is unchanged.
• Removed a leftover roxygen stub comment block from R/lat2w.R.
• Added a testthat suite (26 assertions) covering lat2w, w.matrix, moransI, moransI.w, spGini, spGini.w and random.test.data, including the consistency of the two Moran’s I implementations and the additivity of the spatial Gini decomposition.
