Cross-tabulate one or two variables
Arguments
- data
a data frame
- ...
one or two variables, for a one- or two-way cross-tabulation
- w
weight
- percent
for a two-way cross-tabulation, replace counts with row or column percentages
NULL, the default, shows counts rather than percentages
"row" will replace counts with row percentages, summing to 100% across columns within each row
"column" will replace counts with column percentages, adding to 100% across rows within each column
