I have a character vector `dts` containing strings of the form `10/30/2001` and when I try to parse them using the `mdy(dts)` function, it takes over 67 seconds, whereas when I do it with `as.date( dts )` (from the "`date`" package on CRAN ), it takes only 4 seconds, which means `mdy` is at least a factor of 15 times slower than `as.date()`.
