Re: [R] N'th of month working day problem

I assume what you want is not the last data value in each month labelled with the nth day of the month (or the last day of the month if there are fewer than n days) but the last day in the data that is on or prior to the nth of the month. If that is what you want then try this. nth.of.month -
