> tab1(mtcars$cyl, oup = "decreasing", cum.percent = TRUE) # how to make frequency table in r (nicer version) Here my dataset does not have missing labels therefore, it doesn’t change much but it is an important feature of the function. The “epiDisplay” package, however, tells you exactly how many data points are missing values and even gives you the remaining stats of your data with and without including the missing data points. One more thing you may have noticed in the earlier method was that if your data misses some labels for some of the observations, it doesn’t tell you there’s missing values. If, for instance, you wish to know what percentage of cars have 8 cylinders or what fraction of cars have 4 gears, this method allows you to get your answer using the same report. It gives you a highly featured report of your dataset that includes descriptive statistics functions like absolute frequency, cumulative frequencies and proportions. Similarly, a two way frequency table can be generated using numerous functions, however, one other function that I’ll be going over in this tutorial comes in the “epiDisplay” package. The number of ways through which you can perform a simple task in R is exhaustive and each method has its own pros and cons. Generating a More Refined Frequency Table in R This table includes distinct values, making creating a frequency count or relative frequency table fairly easy, but this can also work with a categorical variable instead of a numeric variable- think pie chart or histogram. This table is a little more explanatory with the columns and rows labeled.
