network

network is a skill for Claude Code, Codex from LeoLin990405/r-analytics-skill. It costs 17 tokens per session (1,030 once invoked), scanned A, original, MIT.

An R package for creating and managing network objects, which represent items and the relationships between them. It supports directed or undirected connections and attributes on nodes and edges.

In plain words
What is it for?
Use it to build networks from edge lists or adjacency matrices, add node and connection attributes, and calculate basic network properties.
Why use it?
It gives network data a structured form so you can inspect its size, density, direction, and attached information.

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

network 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 9d 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.

Creating Networks

library(network)

# From edge list
edges <- matrix(c(1, 2, 1, 3, 2, 3, 3, 4), ncol = 2, byrow = TRUE)
net <- network(edges, directed = TRUE)

# From adjacency matrix
adj <- matrix(c(0, 1, 1, 0,
                0, 0, 1, 0,
                0, 0, 0, 1,
                0, 0, 0, 0), nrow = 4, byrow = TRUE)
net <- network(adj, directed = TRUE)

# Empty network
net <- network.initialize(10, directed = FALSE)

Network Properties

# Number of vertices
network.size(net)

# Number of edges
network.edgecount(net)

# Is directed?
is.directed(net)

# Is bipartite?
is.bipartite(net)

# Density
network.density(net)

Vertex Attributes

# Set vertex attribute
set.vertex.attribute(net, "name", c("A", "B", "C", "D"))
net %v% "name" <- c("A", "B", "C", "D")

# Get vertex attribute
get.vertex.attribute(net, "name")
net %v% "name"

# List all vertex attributes
list.vertex.attributes(net)

Edge Attributes

# Set edge attribute
set.edge.attribute(net, "weight", c(1, 2, 3, 4))
net %e% "weight" <- c(1, 2, 3, 4)

# Get edge attribute
get.edge.attribute(net, "weight")
net %e% "weight"

# List all edge attributes
list.edge.attributes(net)

Network Attributes

# Set network attribute
set.network.attribute(net, "title", "My Network")
net %n% "title" <- "My Network"

# Get network attribute
get.network.attribute(net, "title")
net %n% "title"

Adding/Removing Edges

# Add edges
add.edges(net, tail = c(1, 2), head = c(4, 4))

# Add edge with attributes
add.edges(net, tail = 1, head = 5, names.eval = "weight", vals.eval = 3)

# Delete edges
delete.edges(net, eid = 1)

# Add vertices
add.vertices(net, nv = 2)

# Delete vertices
delete.vertices(net, vid = c(1, 2))

Subsetting

# Get neighbors
get.neighborhood(net, v = 1, type = "out")
get.neighborhood(net, v = 1, type = "in")
get.neighborhood(net, v = 1, type = "combined")

# Get edge IDs
get.edgeIDs(net, v = 1, alter = 2)

# Subnetwork
subnet <- get.inducedSubgraph(net, v = c(1, 2, 3))

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.

network is a skill published in the GitHub repository LeoLin990405/r-analytics-skill (5 stars, last pushed 6mo ago), licensed MIT. It adds 17 tokens to every session and 1,030 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.
