Why R is better than Excel for teaching statistics

Hyndsight

This was the topic of a recent conversation on the Australian and New Zealand R mailing list. Here is an edited list of some of the comments made.

  • R is free.

  • R is well-documented.

  • R runs (really well) on *nix as well as Windows and Mac OS.

  • R is open-source. Trust in the R software is evident by its support among distinguished statisticians. However, the R user need not rely on trust, as the source code for R is freely available for public scrutiny.

  • R has a much broader range of statistical packages for doing specialist work.

  • R has an enthusiastic user base who can offer helpful advice for free.

  • R creates far better graphics than Excel.

  • R has certain data structures such as data frames that can make analysis more straightforward than in Excel

  • R is better for doing complex jobs

  • R is a better educational tool as it uses standard statistical vocabulary rather than home-baked terminology.

  • R is easier to learn, use, and script than Excel.

  • R allows students easily to work with scripts, thus allowing the work to be reproducible.

  • R is intended to lead students towards programming; Excel is designed to keep people away from programming and encourages them to rely on someone else doing their programming (and often their thinking) for them.

  • Excel is known to be inaccurate whereas R is thoroughly tested. For a critique of Excel, see McCullough & Heiser (2008).

  • The statistical package available in Excel is very limited in capability and should only be used by experienced applied statisticians who can work out when its output should be ignored.

  • While R takes a while to learn, it provides a broad range of possible analyses and does not constrain users to a very limited set of methods (as is the case for Excel).
