Julia for Data Science (Video 14)

This video tutorial explores the use of dataframes in data analysis, focusing on importing datasets, using various functions to explore and subset data, applying functions to columns and rows, grouping data by features, and sorting and stacking data. The tutorial uses the iris dataset as an example and demonstrates techniques such as conditional selection, applying aggregate functions, and reverse sorting.
