I think the two most important messages that people can get from a short course are:
a) the material is important and worthwhile to learn (even if it's challenging), and b) it's possible to learn it!
For those reasons, I usually start by diving as quickly as possible into visualisation. I think it's a bad idea to start by explicitly teaching programming concepts (like data structures), because the pay off isn't obvious. If you start with visualisation, the pay off is really obvious and people are more motivated to push past any initial teething problems. In stat405, I used to start with some very basic templates that got people up and running with scatterplots and histograms - they wouldn't necessary understand the code, but they'd know which bits could be varied for different effects.
Apart from visualisation, I think the two most important topics to cover are tidy data (i.e. http://www.jstatsoft.org/v59/i10/ + tidyr) and data manipulation (dplyr). These are both important for when people go off and apply
As far as I know Rstudio does not count words or characters at the moment, which would be useful particularly when writing Rmarkdown.
This is a quick shortcut using word_count and character_count functions from qdap package. See below for two wrapper functions that simplify their use.

| #' This is a wrapper to \code{\link{require}} and \code{\link{install.packages}}. | |
| #' Specifically, this will first try to load the package(s) and if not found | |

| #' installed package version with what is available on CRAN (or mirror) and | |
| #' install the newer version. | |
| #' | |
| #' @param pkgs a character vector with the names of the packages to load. |
