Done already, I see (except the class-header idea, which probably
requires more thought). Thanks.
While we're in there should we perhaps consider adding pseudo-classes
"Ymd"
"dmY"
"mdY"
"Y/m/d"
"d/m-Y"
"m/d/Y"
etc? Or perhaps it is better with a catchall "Date-fmt", i.e., e.g.,
"Date-%Y%m%d"? That'd be fairly easy to code:
else if (length(grep("^Date-",colClasses[i])))
as.Date(data[[i]], sub("^Date-(.*)$","\\1", colClasses[i]))
although perhaps not so easy to document concisely.
