Converting Logical Class to Multiple Variables in the Workspace: A Custom Solution with Precautions
Converting Logical Class to Multiple Variables in the Workspace In this article, we will explore a common problem in R programming: converting logical values from characters to logical vectors. We’ll take a look at different approaches and their trade-offs. Problem Statement When working with multiple variables that need to be converted to logical type, it can be cumbersome to do so individually. In this case, we’re given a dataset with various character strings representing logical values (“TRUE”, “FALSE”) and want to convert them all to logical vectors in the workspace without having to change their class at the beginning.
