[R] Formatting column displays

while working with data I would not touch the formatting of the columns. If
knowing the units is important, you can add it to the column name rather
than the values of the columns.
For presentation purposes - where everything is turned into strings - it is
a different story. Once you are done with your calculations, you can format
everything the way you like it. I find kable() from the knitr package to
help a lot with basic formatting, though you might have to do a little
pre-processing by hand (and here sprintf comes in handy).
And to echo Jeff: you should use Rmarkdown if you are writing up reports
and it is well integrated with Rstudio. knitr works behind the scenes, and
I believe it can even create a Microsoft Word document though pandoc,
without the need for ReporteR (but I have never tried, so I might be wrong).
