Arguments
formula
a formula of the form cbind(col1, col2, ...) ~
cbind(row1, row2, ...). Column and row marginals must have the
same total for each ecological unit.
data
a data frame containing the variables specified in
formula and (optionally) total
rows
a character vector specifying the rows of interest
column
a character string specifying the column marginal of
interest
excluded
an optional character string (or vector of character
strings) specifying the columns to be excluded from the bounds
calculation. For example, if the quantity of interest is Democratic
share of the two-party vote, non-voters would be excluded.
threshold
the minimum proportion of the unit that row members must
comprise for the bounds to be calculated for the unit. If
threshold = 0, bounds will be calculated for all units.
total
if row and/or column marginals are given as proportions,
total identifies the name of the variable in data containing the
total number of individuals in each unit
