ok, to make this easier for people using the rkwarddev package, it now 
(0.05-8) has a new function rk.paste.JS.graph(). it takes care of three 
things:

 - everything is placed between graph.on() and graph.off() (and those in
   "if(full)" conditions)

 - everything is inside a try() call

 - if global plot options are specified, everything is placed between their
   corresponding "preprocess" and "calculate" statements, so you only need
   to place the options inside the actual plot call yourself

i have also added a function called rk.plotOptions() to make the embedding of 
plot options much easier. try the examples in
 ?rkwarddev::rk.plotOptions
 ?rkwarddev::rk.paste.JS.graph
or examine the rkwarddev scripts in the external MDS plugin, which also uses 
rk.plotOptions() to enable text color selection.

interesting, i cannot confirm this: i tried the 2PL plot with activated 
preview, and all options did have an effect here.

done.
