Re: [R] "Holes" in a data frame with time intervals

Try this: dif <- na.omit(c(DF$STARTDATE[-1], NA) - DF$ENDDATE) list(DF$ENDDATE[dif != 1] + 1, DF$ENDDATE[dif != 1] + (dif[dif != 1] - 1)) On Mon, Mar 28, 2011 at 8:56 AM, wrote: > Good morning, > > > > I am facing a problem very easy to solve with a program, but not too > easy (at least IMHO)

[R] "Holes" in a data frame with time intervals

Good morning, I am facing a problem very easy to solve with a program, but not too easy (at least IMHO) with a "declarative" approach. I have a dataframe df with some information about bank branches with a validity time associated (start date/end date, format -MM-DD) to some attributes (fo
