In russHyde/homologiser: Map Genes To Their Homologues In A Different Species

Description

Takes a dataframe, and identifies any entries in a given column ('seed_col') that have more than one associated entry in another column of that data-frame ('target_col').

Usage

which_mappings_are_one_to_many(x, seed_col, target_col, na_rm = TRUE)

Arguments

x	Some data.frame.
seed_col	A single string, one of the column names in x.
target_col	A single string, one of the column names in x.
na_rm	Boolean. Should NA-containing rows be removed from the (seed_col, target_col) sub-dataframe of x before calling one-many status?

Details

NA-containing (seed_col, target_col) pairs are removed prior to determining the number of mappings if 'na_rm=TRUE'.
