Opening steps

Choose your environment or purpose to see its steps.

RStudio

Preserve the original and inspect a working copy in a compatible application.

Inspect settings and sibling files as text.
Open a trusted project folder through its RPROJ.
Check the working directory and project files.

Inspect the received file and its requirements

Establish dependencies and settings before proceeding.

Gather code, data and environment lock files.
Check R and package requirements.
Inspect startup profiles and workspace restoration settings.

Menu labels and support vary by app, OS and version. Preserve the original before making changes.

Troubleshooting by symptom

Empty project: locate separate code/data.
Missing packages: compare environment/version requirements.
Wrong paths: inspect machine-specific absolute references.
Startup error: inspect project startup behavior.

RPROJ → project-directory handoff

Deliver required code, inputs and settings with directory layout intact.
Reopen the output and check it against the preservation points in this guide before handoff.

RPROJ alone cannot restore results or all packages.

Configuration versus analysis output

Render RMD/QMD for reports; converting RPROJ to PDF does not generate analysis.

Worked example: checks before handoff

Example: test the shared folder in a fresh environment using relative paths.

Handling and security

Inspect secrets, private data and startup code in a shared project.

Questions and answers

Does it contain the dataset?

It generally holds settings; data is separate.

Same behavior in another IDE?

Settings support differs.

Is double-click always harmless?

Inspect startup actions and restoration settings.
