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 1...
