## Sample data frame
sex <- sample(c("Man","Woman"),100,replace=TRUE)
jazz <- sample(c(0,1),100,replace=TRUE)
rock <- sample(c(TRUE, FALSE),100,replace=TRUE)
electronic <- sample(c("Y","N"),100,replace=TRUE)
weights <- runif(100)*2
df <- data.frame(sex,jazz,rock,electronic,weights)
## Two-way frequency table on 'music' variables by sex
cross.multi.table(df[,c("jazz", "rock","electronic")], df$sex, true.codes=list("Y"))
