The frequency distribution of a categorical variable can be checked using the table function in R language. Table () function calculates the count of each categories of a categorical variable.
gender=factor(c(“M”,”F”,”M”,”F”,”F”,”F”))
table(sex)
Output of the above R Code –
Gender
F M
4 2
Programmers can also calculate the % of values for each categorical group by storing the output in a dataframe and applying the column percent function as shown below -
t = data.frame(table(gender))
t$percent= round(t$Freq / sum(t$Freq)*100,2)
Gender | Frequency | Percent |
---|---|---|
F | 4 | 66.67 |
M | 2 | 33.33 |
