Hello, Can someone help me on how to make a subset of my dataframe using two dates. This is what I have tried, but no data is being excluded in the new frame. six_months<-subset(Two_years, vdate>2011-01-01|vdate<2011-07-01) or all data is excluded six_months<-subset(Two_years, vdate>2011-01-01&vdate<2011-07-01) -- View this message in context: http://r.789695.n4.nabble.com/Subset-based-on-a-date-range-tp4630595.html Sent from the R help mailing list archive at Nabble.com.

Convert the *string* "2011-01-01" to a date format that corresponds to vdate, see e.g. ?strptime. Uwe ligges
