[R] Vector of weekly dates starting with a given date

[Dimitri Liakhovitski]

Hello!

I have a date (a Monday):

date<-20081229
mydates<-as.Date(as.character(date),"%Y%m%d")

What package would allow me to create a vector that starts with that
date (mydates) and contains dates for 51 Mondays that follow it (so,
basically, 51 dates separated by a week)?

Thanks a lot for the pointer!
