glimpse() is like a transposed version of print():
columns run down the page, and data runs across.
This makes it possible to see every column in a data frame.
It's a little like str() applied to a data frame
but it tries to show you as much data as possible.
(And it always shows the underlying data, even when applied
to a remote data source.)
glimpse() is provided by the pillar package, and re-exported
by dplyr. See pillar::glimpse() for more details.
