Computes a (possibly weighted) contingency table

Description

Computes a contingency table from one or two vectors, with the possibility of specifying weights.

Usage

weighted.table(x, y = NULL, weights = NULL, stat = "freq",
              mar = FALSE, na.rm = FALSE, na.value = "NA", digits = 1)

Arguments

x	an object which can be interpreted as factor
y	an optional object which can be interpreted as factor
weights	numeric vector of weights. If NULL (default), uniform weights (i.e. all equal to 1) are used.
stat	character. Whether to compute a contingency table ("freq", default), percentages ("prop"), row percentages ("rprop") or column percentages ("cprop").
mar	logical, indicating whether to compute margins. Default is FALSE.
na.rm	logical, indicating whether NA values should be silently removed before the computation proceeds. If FALSE (default), an additional level is added to the variables (see na.value argument).
na.value	character. Name of the level for NA category. Default is "NA". Only used if na.rm = FALSE.
digits	integer indicating the number of decimal places (default is 1)

Value

Returns a contingency table.
