If dates is a 2-element Date or POSIXt vector, users won't have to do dates = paste(from, to, sep = "/") if they have start/end times in separate from and to objects. Related to #10.
maybe another option would be to accept any length vector of timebased values and use the min and max of that vector as the from and to. just thinking...
