I want to be able to compute the median of a variable first for the larger data set "timeuse" then for the subset file "subset_1". How do I identify to R which data set I'm wanting the median computed for? I've tried many possibilities but for some reason can't figure it out.
?with
with(timeuse, median(…))
with(subset_1, median(…))
