Add new post about summarising tibbles

[Layalchristine24]

Adding new content to R Weekly issue

In my opinion, the reframe() solution is the best and the easiest one because you do not need to worry about ungrouping the tibble at the end of your pipe (with summarise()) nor joining another summarised tibble (with count()) to obtain the sums of the variables you want.
