inspired by the request the other day, i'm working on an ANOVA plugin. it uses 
ezANOVA() (package "ez"), which supports between/within/mixed models and 
sphericity correction out of the box.

the function needs a data.frame and information which column is what, like

  ezANOVA(data=my.data.frame, dv=.(colDepend), wid=.(varCondition) ...)

so i had to get to these names somehow out of e.g. 
my.data.frame[["colDepend"]]. is there already a simple solution to that? my 
goal is not to produce many lines of R code which a human being would have 
condensed into one simple call, like above.

you can check out its current state here:
 o http://reaktanz.de/stuff/R/anova_plugin.R
it basically works already (you can try the example in ?ezANOVA).

hm, ok, i was under the impression that it's obviously useful ;-) it actually 
is, i'm using it in my plugin (s.a.). but maybe you have a hint how to do that 
more elegant.

sure. i don't know if you had a look at rk.JS.array() and rk.JS.options() yet 
(run the exampes to see JS code), but i was thinking of these two ATM, because 
i've used that in some plugins now.
