The most common and straight forward method of generating a frequency table in R is through the use of the table function. In this tutorial, I will be categorizing cars in my data set according to their number of cylinders. I’ll start by checking the range of the number of cylinders pre...

Therankcolumn here tells us the rank of each word within the frequency table; the table was already ordered bynso we could userow_number()to find the rank. Then, we can calculate the term frequency in the same way we did before. Zipf’s law is often visualized by plotting rank on the...

Background: Running can improve health status from a biopsychosocial perspective. However, isolation strategies, like the COVID-19 pandemic-induced lockdown, produce deleterious effects on both health status and sport performance. The aim of our study wa
