Retrieve cell type markers from the clustermole database.
Usage
clustermole_markers(species = c("hs", "mm"))Value
A data frame of cell type markers with these columns:
gene: Canonical gene symbol for the requested species.gene_original: Original source gene symbol.celltype_full: Full cell type signature identifier.db: Source database.celltype: Cell type label.organ: Organ label.species: Source signature species, if known.n_genes: Gene count per signature.
Details
The gene column uses the official NCBI symbols for the requested species.
The package maps the aliases in each source database to these symbols. The
gene_original column preserves the symbol from the source. The source
databases include both human and mouse cell type markers. The package maps
them across species with ortholog data from the Alliance of Genome Resources
and keeps only reciprocal best matches. The output does not include genes
that have no ortholog in the requested species and does not include
signatures with fewer than five genes.
Examples
markers <- clustermole_markers()
