| map_headers | R Documentation |
robust matching of a list of desired columns to a character array representing column headers
Description
instead of literal string matching between 'headers' and values in l, strip/cleanup both by removing all non-alphanumeric characters and convert to lowercase.
Usage
map_headers(headers, l, error_on_missing = FALSE, allow_multiple = FALSE)
Arguments
headers |
character array representing column names |
l |
list of mappings, where list names are target column names and values are character arrays that are (ordered) valid values to represent a column |
error_on_missing |
throw error if any element in l fails to match |
allow_multiple |
throw error if any element in l has multiple matches |
