get.margins.Loglin(margins, nmes)
list(1:2, 3:4)
would indicate fitting the 1,2 margin (summing over
variables 3 and 4) and the 3,4 margin in a four-way table. This same
model can be specified using the names of the variables (e.g.,
list(c("V1", "V2"), c("V3", "V4"))
), or using formula notation, as in
margins = ~V1:V2 + V3:V4
. When formula notation is used, the
argument
frequency
can be included as the dependent variable (as in
margins = frequency~V1:V2 + V3:V4
).
get.margins.Loglin
).
nmarg
, a vector containing the
margins to be fitted, separated by a single zero, and 2)
iy
, the
column number of the dependent variable in the matrix or
data frame.
This is an internal routine and is not usually called directly by users.
