Counts of two footshape classes on 2513 lambs.
lamb
A data frame with 12 columns and 68 rows:
Cross year, an integer vector with values 1 and 2
A factor with 5 levels
A factor with 2 levels
A factor with 18 levels
A numeric vector
Binomial totals for each sex, sire, group combination
Incidence of footshape class 2
Incidence of footshape class 1
Incidence of scald disease
Incidence of rot disease
Footshape class 2 (l5
) as a proportion
Footshape class 2 failure counts (1-l5
)
The feet of 2513 lambs born in 1980 and 1981 from 5 mating groups were scored in two footshape classes: 1) all four feet are normal, and 2) one foot is deformed. Two indicator variables were also recorded for the presence of the disease conditions scald and rot. The data is grouped into 68 sex, sire and mating group combinations.
