FAQ’s

Which are 5 of the most commonly used dplyr functions?

a) filter(): This function extracts specific rows from a dataset based on given conditions. It allows you to filter observations that meet certain criteria, such as selecting all rows where a variable satisfies a specific condition.

b) select(): The select() function is used to choose specific columns or variables from a dataset. It enables you to extract only the columns of interest, facilitating data exploration and analysis by focusing on relevant information.

c) mutate(): The mutate() function allows you to create new variables or modify existing ones within a dataset. It is commonly used to perform calculations, transformations, or derive new insights by adding computed columns to the data.

d) arrange(): With the arrange() function, you can reorder the rows of a dataset based on one or more variables. This function is useful for sorting data in ascending or descending order, facilitating data exploration and identifying patterns.

e) summarize(): The summarize() function is used to compute summary statistics and aggregate values within a dataset. It enables you to calculate metrics such as mean, median, sum, or count for specific variables, providing a concise data summary.
