Modifying Variable Length Strings in R ===================================================== In this article, we will explore how to modify variable length strings in R without reordering the vector. We will use a combination of string manipulation functions from the stringi library and R’s built-in indexing capabilities. Problem Statement The problem is that when modifying variable length strings, the positions within the vector are changed, leading to incorrect results. For example, in the given code, “C0200s” has moved from its original position to become “A1312s”.
