The usual way of teaching R seems to be bottom-up. Here's the command prompt, type some arithmetic, make some assignments, learn about function calls and arguments, write your own functions, write your own packages.
Perhaps a top-down approach might help certain cases. People using point-n-click packages tend to use a limited range of analyses. Write some functions that do these analyses, or give them wrappers so that they get something like:
> myData = readDataFile("foo.dat")
Read 4 variables: Z, Age, Sex, Disease> analyseThis(myData, response="Z", covariate="Age")
Z = 0.36 * Age, Significance level = 0.932
or whatever. Really spoon feed the things they need to do. Make it really easy, foolproof.
Then show them what's behind the analyseThis() function. How its not even part of the R distribution. How easy you made it for a beginner to do a complex and novel analysis. Then maybe it'll "click" for them, and they'll see how having a programming language behind their statistics functions lets them explore in ways not thought possible with the point-n-click paradigm. Perhaps they'll start editing analyseThis() and write analyseThat(), start thinking for themselves.
Or maybe they'll just stare at you blankly...
