Hello!
The code below works and does what I need it to do.
However, I think the way I create myframe (last step) is very
un-R-like and probably not very efficient. I am sure there are better,
more R-appropriate methods.
Any pointers?
Thanks a lot!

# Step 1: Creating a vector of dates:
mydates<-seq(as.Date("2008-12-29"), length = 50, by = "week")
(mydates)
# Step 2: Creating a vector of units:
units<-1:20
(units)
### Step3: Creating a data frame with 2 columns: all units stacked
(col 1) with all dates in each (col 2):
myframe<-NULL
for(i in 1:length(units)){ # i<-1
myframe[[i]]<-data.frame(unit=rep(units[i],length(mydates)),Weeks=mydates)
}
myframe<-do.call(rbind,myframe)
str(myframe)
head(myframe,110)
