Hi all, <div><br></div><div>I often have a date index in a data frame that I don't really care to keep as a time series because I don't do any sort of smoothing or anything, but I prefer to keep it as a date class (or POSIXct or whatever) so I can do things like only get data past a certain date, or so plots will format correctly.</div>
<div><br></div><div>I've found that any time I time to make a date class a key variable it complains that it can't be converted to integer without losing information. I've had to resort to saving them as factors and then using as.POSIXct whenever i want them as dates, which is annoying and error prone.</div>
<div><br></div><div>Does anyone have a better way? POSIXct supports all standard equality functions, and (I'm pretty sure) you can just convert into unix seconds without losing anything, so why does it complain?</div>
