Escaping special characters #6

Closed jimhester closed 10 years ago

jimhester commented 10 years ago

we currently don't do any escaping of special characters, probably will want to to avoid confusion.

jimhester commented 10 years ago 
ESCAPED_CHARS = c('*', '.', '?', '^', '+', '$', '|', '(', ')', '[', ']', '{', '}')
gsub(p('([\\', p(collapse='\\', ESCAPED_CHARS),'])'), '\\\\\\1', p, perl=TRUE)

Is how I did it before...
