Viewing Package Details

The package details page shows everything Posit Package Manager knows about a single package across an R, Bioconductor, Python, or Open VSX repository. Use it to inspect a package before installing it, copy install commands, audit security and licensing, browse historical versions, and follow links out to upstream sources.

To open it, search or browse packages on the Packages page (see Searching for Packages) and select a result.

Page anatomy

The page uses a two-column layout below a row of tabs:

• Sidebar — at-a-glance facts. Install code, publisher, license, links, identifiers, downloads, and other reference data.
• Main column — expandable sections that carry the bulk of the content. README, dependencies, vulnerabilities, metadata, and so on. Expandable sections remember their open and closed state across page refreshes for the rest of your browsing session.
• Tab row — switches the layout between different views of the same package.

Note

The exact contents of the sidebar and main column depend on the package type. Each tab subsection below explains what changes per repository type.

Tabs

Every package details page has at least one tab — Overview — and may also have several others depending on the repository type and the package itself.

Tab Name	When it appears	What it shows
Overview	Always	The default view: install code, key facts, README, dependencies, vulnerabilities.
Other Versions	Always	Every release of the package this repository serves.
History	R, Bioconductor, and Python repositories	A chronological timeline of when each version became available, with snapshot URLs for reproducibility.
Changelog	Open VSX extensions that publish a changelog	The extension’s release notes, rendered inline.
Custom Tabs	Packages with tab.* metadata configured by an administrator	Administrator-configured links or embedded views, one tab per metadata entry.

Note

The Overview and Other Versions tabs are always present. Other tabs only appear when there is something to show — for example, the Changelog tab is hidden on extensions that do not publish a changelog file.

Status banners

Blocked, deprecated, and preview packages show a banner at the top of the main column with the relevant reason. The Security Vulnerabilities section auto-expands on blocked packages so the cause is visible without an extra click.

Status banners that may appear:

• Blocked — an administrator has blocked this package, or this specific version, via a blocklist rule. The banner shows the rule description.
• Deprecated (Open VSX only) — the publisher has marked the extension as no longer maintained.
• Preview (Open VSX only) — the publisher has marked the extension as experimental and subject to change.

Returning to search

A Back to Search Results button at the top of the page returns you to the search list with your query and page number preserved. If you arrived at the page from a direct link instead of a search, the button reads View All Packages (or View All Extensions for Open VSX) and takes you to the unfiltered list.
