Background The openxlsx package provides a comprehensive set of functions for creating, editing, and manipulating Excel files in R.
Using an "Or" Conditional in the `n_distinct` Function of Dplyr: A Flexible Approach to Summarize Counts for Multiple Conditions
Using an “Or” Conditional in the n_distinct Function of Dplyr In this article, we will explore how to use an “or” conditional in the n_distinct function from the dplyr package. We will also discuss how to summarize counts for multiple conditions.
Introduction to the Problem Suppose we start with a data frame called mydat, which contains information about individuals and their status. The task is to calculate the number of unique IDs by Period and Status_1 where Status_2 is either “Open” or “Terminus”.
Dynamic Dataframe Naming with Dplyr and R: Flexible and Readable Ways to Work with Dataframes
Dynamic Dataframe Naming with Dplyr and R When working with dataframes in R, it’s often necessary to dynamically create or name them based on specific conditions. In this article, we’ll explore how to achieve dynamic dataframe naming using the dplyr library.
Understanding Dplyr and its Benefits The dplyr library is a popular data manipulation tool in R that provides a grammar of data manipulation. It’s designed to make data analysis more efficient, flexible, and readable.
