Splitting Data Frame Rows Based on Overlap Calculation with data.table Package in R
Introduction The problem presented in the Stack Overflow post is to split a data frame row into two rows based on a separate table. The goal is to perform an overlap check between two intervals (the original data and reference table) and then split the values proportionally between the overlapping parts.
In this blog post, we will explore how to achieve this using the data.table package in R. We’ll go through each step of the process, including keying both datasets by chromosome and interval columns, running the foverlaps function, and updating the start and end values according to the overlap.

Resolving R Package Loading Issues: A Step-by-Step Guide to Using `emmeans`
The problem you are experiencing is likely due to the way R loads packages. When you import or use a function from another package without explicitly loading that package, R may try to load it automatically if the package is not already loaded.
In your case, it seems that the emmeans package is being used, but it is not explicitly loaded. This can cause R to look for an emmeans package in the default search paths (e.
