 Greetings,


 I have a groupedData (nmGroupedData) object created with the following syntax:

   units=list(x='(cmol_c)', y='(cm/s)')
 )


 the original data represents longitudinal observations in the form of:
 'data.frame':   1197 obs. of  5 variables:
  $ soil_id: Factor w/ 19 levels Arbuckle,Campbell,..: 16 16 16 16
 16 16 16 16 16 16 ...
  $ sar: int  12 12 12 12 12 12 12 6 6 6 ...
  $ conc   : num  500 100 50 10 5 1 0.003 500 100 50 ...
  $ rep: Factor w/ 3 levels C1,C2,C3: 1 1 1 1 1 1 1 1 1 1 ...
  $ ksat   : num  0.000214 0.000207 0.000198 0.000160 0.000108 ...

 the default plotting behaviour of this groupedData object works as expected:
 plot(
   Soil,
   collapse=1, inner=~sar, aspect='fill',
   scales=list( x=list(log=TRUE), y=list(log=TRUE))
 )

 ... however, there is no way for me to alter the panels...

 for example, attempting to add a horizontal line with a call to
 panel.abline= ... :
 plot(
   Soil,
   collapse=1, inner=~sar, aspect='fill',
   scales=list( x=list(log=TRUE), y=list(log=TRUE)),
   FUN=mean,
   panel= function(x,y, subscripts, groups) {
 panel.xyplot(x, y, type='o')
 panel.abline(h=0.005, col='black', lty=2)
 }
 )

 ... results in an identical plot. Trying to re-create the results of
 plot.nmGroupedData with a direct call to xyplot() has thus far been
 unsucsessful- as I cannot figure out how to specifiy the original
 formula in a meaningful way to xyplot: ksat ~ conc | soil_id/sar/rep .

You might try something like

ksat ~ conc | soil_id:sar:rep

(also see ?interaction for a version with more control)

Any tips on passing panel arguments to plot.nmGroupedData() would be
greatly appreciated.
