Hello, How can I create a symmetric contingency table from two categorical vectors having different length of levels? For example one vector has 98 levels TotalData1$Taxa.1 [1] "Aconoidasida" "Actinobacteria (class)" "Actinopterygii" "Alphaproteobacteria" [5] "Amoebozoa" "Amphibia" "Anthozoa" "Aquificae (class)" and so on ......... 98 Levels: Aconoidasida Actinobacteria (class) ....
and the other vector has 105 levels TotalData1$Taxa.2 [1] Flavobacteria Proteobacteria Bacteroidetes/Chlorobi group Bacteria [5] Epsilonproteobacteria Epsilonproteobacteria Epsilonproteobacteria and so on .......... 105 Levels: Acidobacteria Aconoidasida Actinobacteria (class) .... Now I want to create a symmetric contingency table. Any quick idea will be really helpful.
