Get Dates of a Certain Weekday from a Year in R

Question

How might I generate a list of date objects (POSIXct or lt) for each Monday of a year?

For instance this year would be (In Year, Month, Day):

2012_01_02,
         


        

Answer 1

I found seq.Date which is part of base. Not sure if there are caveats to this method but it seems to do what I want:

x = seq(as.Date("2012/01/02"), as.Date("2013/01/01"), "7 days")
as.POSIXct(x)
