In Data Science from Scratch, a book introducing data science using Python, Joel Grus said the following about R (pg. 302):
Although you can totally get away with not learning R, a lot of data scientists and data science projects use it, so it’s worth getting familiar with it.
In part, this is so that you can understand people’s R-based blog posts and examples and code; in part, this is to help you better appreciate the (comparatively) clean elegance of Python; and in part, this is to help you be a more informed participant in the never-ending “R versus Python” flamewars.
I submitted the following as a letter to the editor of the Salt Lake Tribune. Chances are it will not be published, so I share it below.
I rely on FiveThirtyEight to tell me the direction of the election, and a few weeks ago, Utah suddenly became very interesting. Evan McMullin, a previously unheard of candidate for President (who entered the race only a few months before Election Day), appeared in Utah’s forecast numbers with a surprisingly large probability of winning Utah’s electoral votes. Benjamin Morris then wrote about how Evan McMullin could plausibly not only win Utah’s electoral votes, but the Presidency as well.
