Understanding the Transitivity of pivot_longer() and pivot_wider() in R: A Solution Using rowid_to_column()
Understanding the Transitivity of pivot_longer() and pivot_wider() In recent years, the tidyr package has become a staple in R data manipulation. Two of its most powerful functions are pivot_longer() and pivot_wider(). These two functions form a crucial pair in transforming data from wide to long format and vice versa. However, when it comes to handling nested objects and ensuring transitivity between these transformations, there is limited information available. This article aims to delve into the details of pivot_longer() and pivot_wider() and explore their behavior with respect to transitivity.

Linear Optimization Using Binary Variables in R: A Practical Guide with Real-World Examples and Code
Linear Optimization Using Binary Variables in R Introduction Linear programming (LP) is a method used to optimize a linear objective function, subject to a set of linear constraints. In this article, we will explore how to use binary variables in linear optimization using the lpSolveAPI package in R. What are Binary Variables? In linear programming, binary variables are variables that can take on only two possible values: 0 or 1. This is useful when modeling problems where a variable can be either present (1) or absent (0).
