Fit Log-Linear Models by Iterative Proportional Scaling -- Internal function

loglm1 is an internal function used by loglm. It is a generic function dispatching on the data argument.

loglm1(formula, data, ...)

# S3 method for xtabs
loglm1(formula, data, ...)

# S3 method for data.frame
loglm1(formula, data, ...)

# S3 method for default
loglm1(formula, data, start = rep(1, length(data)), fitted = FALSE,
       keep.frequencies = fitted, param = TRUE, eps = 1/10,
       iter = 40, print = FALSE, ...)

Arguments

formula	A linear model formula specifying the log-linear model. See loglm for its interpretation.
data	Numeric array or data frame. In the first case it specifies the array of frequencies; in then second it provides the data frame from which the variables occurring in the formula are preferentially obtained in the usual way. This argument may also be the result of a call to xtabs.
start, param, eps, iter, print	Arguments passed to loglin.
fitted	logical: should the fitted values be returned?
keep.frequencies	If TRUE specifies that the (possibly constructed) array of frequencies is to be retained as part of the fitted model object. The default action is to use the same value as that used for fitted.
...	arguments passed to the default method.

Value

An object of class "loglm".
