by ADMIN 64 views

Introduction

RStudio is a popular integrated development environment (IDE) for R programming language. It provides a comprehensive set of tools for data analysis, visualization, and modeling. However, with the recent update to RStudio 2025.05.0, users have reported a peculiar issue where the IDE continues to execute code after an error occurs in R Markdown files. In this article, we will delve into the details of this issue, explore the possible causes, and discuss the expected behavior.

System Details

To reproduce the problem, we need to understand the system configuration. The following details are provided:

  • RStudio Edition: Desktop
  • RStudio Version: 2025.05.0+496
  • Platform: aarch64-apple-darwin20
  • OS Version: MacOS 15.4.1 (24E263)
  • R Version: 4.5.0

Steps to Reproduce the Problem

To reproduce the issue, follow these steps:

  1. Open an R Markdown file in RStudio.
  2. Enable the global RStudio option "Console -> Discard pending console input on error".
  3. Run a block of code that causes an error (e.g., an undefined object).
  4. Observe that the first part of the error message is meaningful, followed by additional lines seemingly unrelated to the initial error.

Describe the Problem in Detail

The problem arises when executing R Markdown files with the global RStudio option "Console -> Discard pending console input on error" enabled. Despite the option, subsequent lines of code continue to be executed after the error, which is unexpected behavior.

Describe the Expected Behavior

The expected behavior is that execution should be stopped after the error message, following the global option to "Discard pending console input on error". This option applies when executing from an R code file, but it does not seem to work as expected in R Markdown files.

Possible Causes

The change in behavior may be caused by the recent update to RStudio 2025.04.11. Before this update, R Markdown execution halted on errors for some users. It is unclear whether this is a bug or an intended change in (default) behavior.

QA Notes

To validate the change, follow these steps:

  1. Install the latest version of RStudio.
  2. Open an R Markdown file and enable the global RStudio option "Console -> Discard pending console input on error".
  3. Run a block of code that causes an error.
  4. Observe the behavior and note whether execution continues after the error.

Conclusion

The issue of RStudio 2025.05.0 continuing execution after an error in R Markdown files is a peculiar problem that requires further investigation. The expected behavior is that execution should be stopped after the error message, following the global option to "Discard pending console input on error". If you are experiencing this issue, please provide more details and follow the QA notes to help validate the change.

Recommendations

To resolve this issue, consider the following recommendations:

  1. Update RStudio: Ensure that you are running the latest version of R.
  2. Check Global Options: Verify that the global RStudio option "Console -> Discard pending console input on error" is enabled.
  3. Review R Markdown Files: Inspect your R Markdown files for any errors or issues that may be causing the problem.
  4. Seek Support: If the issue persists, contact RStudio support for further assistance.
