See liquidation cascades before they happen — for R. install.packages("wickraradar", repos = "https://wickra-lib.r-universe.dev") — over the C ABI via .Call, prebuilt library fetched on install.

R bindings for the wickra-radar data-driven core, over its C ABI hub (.Call). Build a radar from a spec JSON, drive it with command JSON, read back the report — the same protocol as the CLI and every other binding.

Install

From r-universe:

install.packages("wickraradar", repos = "https://wickra-lib.r-universe.dev")

The package's configure downloads the prebuilt C ABI library for this exact version from the GitHub release and bundles it, so an ordinary install needs nothing but a C toolchain (Rtools on Windows) for the thin .Call glue layer. To build against a local checkout instead, point it at the header and library with the environment variables below.

Building from this repository (contributors)

The package links the wickra_radar C ABI, located out-of-tree via two environment variables:

# Build the C ABI shared library first.
cargo build -p wickra-radar-c --release

export WKRADAR_INC="$PWD/bindings/c/include"
export WKRADAR_LIB="$PWD/target/release"
# The loader must also find the shared library at run time:
export LD_LIBRARY_PATH="$WKRADAR_LIB:$LD_LIBRARY_PATH"   # PATH on Windows

R CMD INSTALL bindings/r
Rscript bindings/r/tests/run_tests.R

Quick start

library(wickraradar)

spec <- paste0(
  '{"symbols":["AAA"],"signals":[{"kind":"funding_flip",',
  '"params":[0.0005]}],"threshold":0.0}'
)

radar <- wkradar_new(spec)
report <- wkradar_command(radar, paste0(
  '{"cmd":"scan","events":{"AAA":[',
  '{"kind":"derivatives","ts":1,"open_interest":1.0,"funding_rate":0.0003,"mark_price":50.0},',
  '{"kind":"derivatives","ts":2,"open_interest":1.0,"funding_rate":-0.0004,"mark_price":50.0}]}}'
))
cat(report, "\n")
cat(wkradar_version(), "\n")

API

Function	Description
`wkradar_new(spec_json)`	Build a radar from a spec JSON (errors on an invalid spec).
`wkradar_command(radar, cmd_json)`	Apply a command JSON, return the response JSON.
`wkradar_version()`	The library version.

Domain errors (a bad spec, an unknown command) come back in-band as {"ok":false,"error":...} JSON.

Benchmark

Every binding forwards to the same data-driven Rust core, so what this one adds is the call overhead of R's native .Call interface over the C ABI, not a different result. The core's throughput is measured by the repository's benchmark suite and the nightly bench.yml run; the numbers, the machine and how to reproduce them are in the repository BENCHMARKS.md.

Documentation

The full guide, the spec reference and the API documentation live in the main repository and the documentation site:

Docs (guides, spec reference, cookbook): https://radar.wickra.org
Runnable example: examples/r/

Wickra Radar ships native bindings for Python, Node.js, WASM and Rust, plus a C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against — all forwarding to the same data-driven, unsafe-forbidden Rust core.
