utilities for approximate matching of cell type terms to GO categories and annotations

cellTypeToGO(celltypeString, gotab, ...)

cellTypeToGenes(
  celltypeString,
  gotab,
  orgDb,
  cols = c("ENSEMBL", "SYMBOL"),
  ...
)

Arguments

celltypeString: character atom to be used to search GO terms using
gotab: a data.frame with columns GO (goids) and TERM (term strings) agrep
...: additional arguments to agrep
orgDb: instances of orgDb
cols: columns to be retrieved in select operation

Value

data.frame

Note

Very primitive, uses agrep to try to find relevant terms.
