breakInNamespace

Read Original

This technical blog post details a specific bug in R's tidyverse related to the !! and !!! quasiquotation operators. The author explains how parsing and deparsing these operators (e.g., when using fix(), fixInNamespace(), or debugging) can corrupt code, producing incorrect nested ! calls. It covers the root cause in the R interpreter/deparser and its impact on package development and debugging workflows.
