All,
Some trial and error follows ( for anyone who cares ).
The case seems that groupedData does not like
to have both "a grouping" and "an outher" defined at the same time.
library(nlme)
d.x <- read.table(header=TRUE, text="
o g h i d
A C E G 1.0
A C E H 2
A C F G 4
A C F H 8
A D E G 16
A D E H 32
A D F G 64
A D F H 128
B C E G 256
B C E H 1024
B C F G 2048
B C F H 4096
B D E G 8192
B D E H 16384
B D F G 32768
B D F H 65536
", stringsAsFactors = FALSE)
# desirable 'outer' ommitted ( but I want 'outer' )
gd <- groupedData(formula = d ~ h | g
, data = d.x
, inner = ~ i
)
# best (available) solution
gd <- groupedData(formula = d ~ h | o/g
, data = d.x
, inner = ~ i
)
> str(gd, vec.len = 16)
