     21 \details{
     22 This is meant to be useful when developing a vector of regexes to 
     23   apply to text. Regular expressions can be appended to \code{patterns}
     24   interactively until the edge cases are all covered, and then
     25   \code{patternapply()} can be deployed to extract data.
