The process for altering the structure of a data frame entails performing various operations, such as:

  1. Adding columns or rows to the data frame using the functions cbind() and rbind(), respectively.

  2. Removing columns or rows from the data frame using the functions subset() and drop.

  3. Renaming columns in the data frame using the function names().

  4. Reordering columns in the data frame using indexing.

  5. Merging or joining multiple data frames using the functions merge() and join().

  6. Reshaping the data frame using functions like melt() and pivot_table().

  7. Changing the data type of columns using the functions as.character(), as.numeric(), and so on.

  8. Dealing with missing values in the data frame using the functions is.na(), complete.cases(), and so on.

  9. Transforming categorical variables into factors using the function factor().

  10. Creating new variables based on existing variables using the function mutate() in the dplyr package.
