tab.cross: Cross-table
In antongrau/soc.report: Tools and functions for reports in social science

tab.cross performs a simple two-way cross tabulation of two factor vectors. Easy printing and plotting is helped by simple formatting.

1 2	tab.cross(x, y, frequencies = TRUE, prop.margin = 1, digits = 2, sum.margin = 1:2, sum.label = "Total")

`x`	a factor
`y`	a factor
`prop.margin`	index, or vector of indices to generate margin for, prop.table
`digits`	the maximum number of digits, round
`sum.margin`	vector of dimensions over which to form margins. Margins are formed in the order in which dimensions are specified in margin. addmargins
`sum.label`	is the label of the margins
`freq`	if TRUE frequencies placed within ()
