Applied autoformatting

I'm used to applying autoformatting when making changes, so that there is a consistent codestyle throughout the project. So I tweaked my formatters (PyCharm for .R and CLion for .cpp) to match some style, which was already used in your code. But because there were multiple different styles and some spaces were not in place, there are some changes.

By the way, Github shows wrong diffs, there are no real code changes, just spaces and newlines moved around.

It would also be good to conform to a styleguide, for the styling to be familiar to everyone and the code easy to read.
This is a common one, as far as I've heard: https://style.tidyverse.org/index.html. There are also automatic tools for it, lintr and styler. However, there would be more changes than spaces, names of files, variables and functions being the most damaging. But it's better to do it sooner than later. I can apply it when (and if) you are ready and agree.
