Which R time/date class and package to use?

Hello,

I want to use a time date format for R, but there are so many packages that have their own format that I am a bit lost.

I was thinking of using the POSIXct/POSIXlt format. Is it the best (flexible enough for all use)

Thanks

Answer 1

Date and POSIXct are both Base R types and highly recommended.

Packages such as zoo or xts use these types for indexing. Other packages like lubridate use them for date computation and parsing.

So your intuition was right: use Date and POSIXct.
