%description
Facilitates population-level analysis of ligand-receptor (LR) interactions
using large-scale single-cell transcriptomic data. Identifies significant
LR pairs and quantifies their interactions through correlation-based
filtering and projection score computations. Designed for large-sample
single-cell studies, the package employs statistical modeling, including
linear regression, to investigate LR relationships between cell types. It
provides a systematic framework for understanding cell-cell communication,
uncovering regulatory interactions and signaling mechanisms. Offers tools
for LR pair-level, sample-level, and differential interaction analyses,
with comprehensive visualization support to aid biological interpretation.
The methodology is described in a manuscript currently under review and
will be referenced here once published or publicly available.
