[R] extra panel arguments to plot.nmGroupedData {nlme}
Greetings, I have a groupedData (nmGroupedData) object created with the following syntax: Soil - groupedData( ksat ~ conc | soil_id/sar/rep, data=soil.data, labels=list(x='Solution Concentration', y='Saturated Hydraulic Conductivity'), 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.

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