Newbie: Subsets of data frame
I feel a bit embarassed by this, but I have not managed to find out how:
I have a data frame containing measurements over time for a number of
different locations:
> str(milk)
`data.frame': 845 obs. of 3 variables:
$ date : num 1987 1987 1987 1987 1987 ...
$ value : num 5 1 2 5 1 1 2 3 2 4 ...
$ location: Factor w/ 36 levels "Alta","And?y",..: 1 1 1 1 1 1
