[R-SIG-Finance] Time given the week number and year.

[Kalisbek K Malikov]

You can try this:
as.Date(paste("2011-01","-01", sep=""))
[1] "2011-01-01"
Hope this helps.
Kalis.

Subject: [R-SIG-Finance] Time given the week number and year.

I am trying to convert from a week number and year to a date. The first thing I try

strptime("2011-01", "%Y-%W")

gives me:

[1] "2011-10-10"

This is wrong as the first week of the year is not in October. Any suggestions on how I can do this conversion?

Thank you.

Kevin
