Performs a very naive guess of the DelimitedFormat.
Performs a very naive guess of the DelimitedFormat. This uses weighted frequencies of occurences of common separators, row-delimiters, quotes, quote escapes, etc. and simply selects the max for each. For empty values, it uses the frequency of the the possible empty values within the cells.
This supports:
* \r\n and \n as row delimiters, * ',', '\t', ';', and '|' as field delimiters, * '"', and as quote delimiter, * the quote delimiter or \ for quote escapes, * , '?', '-', 'N/A', and 'NA' as empty values, and * 'N/M' and 'NM' as invalid values.
Headers are guessed by using the cosine similarity of the frequency of characters (except quotes/field delimiters) between the first row and all subsequent rows. Values below 0.5 will result in a header being inferred.
Makes a guess at the format of the CSV accessed by reader.
Makes a guess at the format of the CSV accessed by reader. This returns
the format, as well as the a new pushback reader to be used in place of
reader. The original reader will have some data read out of it. The
returned reader will contain all the original reader's data.
