getLDscores

This function retrieves LD scores from a structured list (`Glist`) that includes
LD scores, chromosome information, and SNP identifiers. You can extract all LD scores
or filter them by a specific chromosome and/or SNP identifiers (rsids).

Provides an infrastructure for efficient processing of large-scale genetic and phenotypic data including core functions for: 1) fitting linear mixed models, 2) constructing marker-based genomic relationship matrices, 3) estimating genetic parameters (heritability and correlation), 4) performing genomic prediction and genetic risk profiling, and 5) single or multi-marker association analyses.

getLDscores function

<dl><dt>Glist</dt>
<dd>A list structure containing genotypic data, including rsids for LD calculation (`rsidsLD`), LD file locations (`ldfiles`), and `msize` which indicates the size for surrounding region to consider for LD.</dd>
<dt>chr</dt>
<dd>A specific chromosome from which LD sets need to be extracted.</dd>
<dt>rsids</dt>
<dd>A vector of rsids that need to be included in the sparse LD matrix. Default is NULL, implying all rsids in the chromosome will be used.</dd></dl>
