Imagine you’ve received a large spreadsheet with messy but important data, and you know it’s got a story to
tell. You spend lots of time cutting and pasting, writing formulas, and data “cleaning.” One problem you’re
fixing is multiple versions of the same company’s name: XYZ, XYZ Inc., X YZ Company, and so on. But
when you’re finally able to do your analysis, something looks wrong. And when you ask your source about it,
he responds: Yes, sorry, there was a mistake in the data file. We’ll send you a corrected spreadsheet shortly.
That was me a few years ago. After swearing (mostly to myself) in the newsroom, I had to re-create everything
I did in that first Excel file in the second. The copying. The pasting. The formula-writing. The painfully
long waits for formulas to execute. Spot checks of results. Standardizing on one version of each company’s
name so counts were accurate.
I vowed that wasn’t going to happen again.
And I started learning R.

Heaven Is Empty: A Cross-Cultural Approach to
In the past few decades, discussions on the role of religion in shaping the
interconnections of politics, society, and culture have acquired a particular
urgency. Since the end of the Cold War, after 9/11, and even more so with
