renv

renv is a skill for Claude Code, Codex from LeoLin990405/r-analytics-skill. It costs 22 tokens per session (931 once invoked), scanned A, original, MIT.

A project tool for managing R package dependencies in an isolated environment. It records the exact packages and versions an R project needs in a lockfile.

In plain words
What is it for?
Use it to initialise an R project environment, record installed packages, and restore dependencies on another computer.
Why use it?
It prevents projects from breaking when package versions differ between computers. Collaborators can recreate the same environment from the lockfile.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

renv scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

renv

Project-local R dependency management.

Initialize Project

library(renv)

# Initialize renv in project
renv::init()

# Creates:
# - renv.lock (lockfile)
# - renv/ directory
# - .Rprofile (auto-activation)

Workflow

# 1. Initialize project
renv::init()

# 2. Work on project, install packages
install.packages("dplyr")

# 3. Snapshot dependencies
renv::snapshot()

# 4. Share project (commit renv.lock)

# 5. Collaborator restores environment
renv::restore()

Snapshot

# Snapshot current state
renv::snapshot()

# Snapshot specific packages
renv::snapshot(packages = c("dplyr", "ggplot2"))

# Snapshot with prompt
renv::snapshot(prompt = TRUE)

# Types of snapshots
renv::snapshot(type = "implicit")  # Used packages only
renv::snapshot(type = "explicit")  # DESCRIPTION only
renv::snapshot(type = "all")       # All installed

Restore

# Restore from lockfile
renv::restore()

# Restore specific packages
renv::restore(packages = c("dplyr"))

# Clean restore (remove unlisted packages)
renv::restore(clean = TRUE)

Package Management

# Install packages
renv::install("dplyr")
renv::install("tidyverse")

# Install from GitHub
renv::install("tidyverse/dplyr")

# Install specific version
renv::install("[email protected]")

# Install from local source
renv::install("./path/to/package")

# Update packages
renv::update()
renv::update("dplyr")

# Remove packages
renv::remove("unused_package")

Status and Diagnostics

# Check status
renv::status()

# View dependencies
renv::dependencies()

# Check for issues
renv::diagnostics()

# View lockfile
renv::lockfile_read()

Lockfile

# View lockfile contents
lockfile <- renv::lockfile_read()
lockfile$Packages

# Modify lockfile
renv::record("[email protected]")

# Validate lockfile
renv::lockfile_validate()

Configuration

# Settings in .Rprofile or renv/settings.dcf

# Use binary packages
renv::settings$use.cache(TRUE)

# Set repository
renv::settings$repos(c(CRAN = "https://cloud.r-project.org"))

# Ignore packages
renv::settings$ignored.packages(c("devtools"))

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

renv is a skill published in the GitHub repository LeoLin990405/r-analytics-skill (5 stars, last pushed 5mo ago), licensed MIT. It adds 22 tokens to every session and 931 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
