[R] Date as Integer

[John Kane]

Do an str() on the data. It looks like your variable is an integer where you probably need a date or a factor.

Would you please include some sample data if possible. See ?dput which is the preferred way for sending sample data. It ensures that the reader is looking at the exact same data that you have on your machine.  

If the data set is large a small, representative sample is find. Something like dput(head(dat1, 100)) is probably fine. Fake data is okay if it is in the same format as the real.  Check with str() before sending.
