Compare dates in R

Post date: Aug 7, 2014 9:36:08 PM

Here is how:

## pattern 1 -- compare variable with date constant

mds.df$eval_date >= as.POSIXct("2014-08-05 18:00:00 PDT")

## pattern2 -- compare between data constants

as.POSIXct("2014-08-05 11:58:54 PDT") < as.POSIXct("2014-08-05 11:59:20 PDT")
