select a set of elements from a term 'map' and return a contribution to a data.frame

Usage

selectFromMap(namedvec, index)

Arguments

namedvec

named character vector, as returned from mapOneNaive

index

numeric() or integer(), typically of length one

Value

Examples

#co = ontoProc::getCellOnto()
co = getOnto("cellOnto", year_added="2023")
#> loading from cache
mast = mapOneNaive("astrocyte", co)
selectFromMap(mast, 1)
#>       ontoid      term
#> 1 CL:0000127 astrocyte
