Description

For US numbers those numbers that are 14 charcaters are converted to 15 characters through the addition of a padding zero after CCYYYY.

Usage

Arguments

x	a data.frame
col	A column containing publication numbers to be transformed.

Details

Be careful when using this function as it is not thoroughly tested. Also be careful that for existing mixed datasets conversion may duplicate an existing derwent innovation number.

Value
