> -Hello, This seems to be a problem that crops up from time to time. I wrote a small function that got the ISO week of a Date object, that you can find in a bug-fixed version here: http://tolstoy.newcastle.edu.au/R/e10/help/10/05/5588.html Hope this is of help. I agree that it would be of interest to incorporate OS-independent date management in R, but not being part of the R development team, I'm not sure how to go about implementing it...
