According to the text of the MIT license:
The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
However, many R packages, seem to follow the note from R packages
A name of a license “template” and a file containing specific variables. The most common case is MIT + file LICENSE, where the LICENSE file needs to contain two fields: the year and copyright holder.
and include only a file of this form (this particular is taken from popular magrittr package)
YEAR: 2019 COPYRIGHT HOLDER: Stefan Milton Bache and Hadley Wickham
without a full text of the license.
What is going on here? Does it violate MIT license requirements?
