This is simply a wrapper around match or %in% for a specific data.frame of values.

equivalentName(value, df, column, multi = FALSE, searchColumn = NULL)



Vector of values to match in df.


A data.frame where every row is a set of equivalent names.


A character string or numeric of length 1, indicating the column in df to return names from.


Logical. If TRUE, then all matches will be returned. Default is FALSE for backwards compatibility. This may result in more elements than were in value, as each value may be matched by more than one entry, returning more than one result each from column. If a species is found in the df, but there is no corresponding value in column, it will return NA


Optionally, provide the name of a column in df that results must be found in. The return value will still be from column
