When dealing with complex and disorganized datasets, it can be overwhelming to know where to begin. However, the tidyr package offers a solution by enabling you to efficiently organize and clean up these unruly datasets. This package effectively converts inaccessible values stored in column names into rows, transforms JSON files into data frames, and ensures that missing values are properly accounted for. Throughout this course, you will have the opportunity to practice these techniques on a diverse range of messy datasets. Along the way, you will discover intriguing facts such as the number of dogs sent into space by the Soviet Union and the most popular bird species in New Zealand. By incorporating the tidyr package into your tidyverse toolkit, you will gain the ability to transform nearly any dataset into a tidy format. This skill will greatly benefit your subsequent data analysis endeavors.
