How do I make a frequency table in R?
table
- You can generate frequency tables using the table( ) function, tables of proportions using the prop.
- table( ) can also generate multidimensional tables based on 3 or more categorical variables.
- Table ignores missing values.
- The xtabs( ) function allows you to create crosstabulations using formula style input.
How do you calculate frequencies in R?
