Re: Code that works outside a custom function but not inside

Thanks everyone for your inputs.

FYI, I found in an old post a solution to my problem with which.panel (which strangely does not have the same behavior as in R!). In the following piece of script, pnl gives the index of the current panel and can be used e.g. to customize the text of the strips.

strip = function(...){
  pnl<-get('n',frame=sys.parent())
  ...
},

Your problem is the mixed-mode model statement

You want to either
       leave out the "data="" phrase
or use
       histogram(~ X|SD,
                  data="">

 Your first statement says "look in the 'mydata' frame for variable names",
but the mydata data frame does not have 'mydata[,1]' as one of its variable
names.  You can get away with this at the top level, where Splus can usually
find things even when given bad directions; but not inside a function.
