Luria Voice system requirements and dependencies

Luria Voice depends on a small set of external tools and R packages. The table below lists every dependency, its minimum version, whether it is required or optional, and where to get it. Detailed install instructions follow.

Requirements at a glance

Dependency	Minimum version	Required	Notes
Quarto	1.4.0	Yes	Bundles Typst — no separate Typst install needed
Typst	Bundled with Quarto	Yes	Do not install separately unless debugging
R	4.2.0	Yes	Earlier versions may work but are untested
dplyr	any CRAN	Yes	Data manipulation
readr	any CRAN	Yes	CSV / data file reading
here	any CRAN	Yes	Portable file paths
yaml	any CRAN	Yes	YAML front-matter parsing
ggplot2	any CRAN	Yes	Figure generation
systemfonts	any CRAN	Yes	Font detection for Typst
cingulate	GitHub (brainworkup)	Yes	Report pipeline utilities
Ollama	any	No	Required only for AI narrative generation

Quarto

Quarto ≥ 1.4.0 is required. Quarto 1.4 introduced the Typst output format that Luria Voice depends on. Download the installer for your operating system from quarto.org. After installing, confirm your version:

quarto --version

The output should be 1.4.0 or higher.

Quarto ≥ 1.4.0 ships with Typst embedded. You do not need to install Typst separately. If you have a standalone Typst installation, Quarto uses its own bundled copy and the two will not conflict.

R

R 4.2 or later is recommended. Download from cran.r-project.org. Confirm your version in R:

R.version$major
R.version$minor

R packages

Install all required CRAN packages in a single command:

install.packages(c(
  "dplyr",
  "readr",
  "here",
  "yaml",
  "ggplot2",
  "systemfonts"
))

cingulate (GitHub)

The cingulate package provides the scoring, norming, and domain-assembly pipeline that populates report sections. It is not on CRAN and must be installed from GitHub.

Install the remotes package

If you do not already have remotes, install it from CRAN:

install.packages("remotes")

Install cingulate from GitHub

remotes::install_github("brainworkup/cingulate")

Verify the installation

library(cingulate)

If this command runs without error, cingulate is installed correctly.

remotes::install_github requires an internet connection and access to GitHub. If you are behind a corporate firewall, contact your IT department to allow outbound connections to api.github.com and codeload.github.com.

Ollama (optional)

Ollama enables AI-generated narrative summaries within the report. It is entirely optional — all scoring, tables, and figures render without it. If you want to use AI narratives:

Download and install Ollama

Download Ollama from ollama.com and follow the installer for your platform.

Pull a model

ollama pull llama3

Start the Ollama server before rendering

ollama serve

Ollama must be running on localhost:11434 when you call quarto render. If it is not running, the narrative generation step will time out and log an error.

Installing everything at once

The following block installs all R dependencies in a single session. Run it once after a fresh R installation.

install.packages(c(
  "dplyr",
  "readr",
  "here",
  "yaml",
  "ggplot2",
  "systemfonts",
  "remotes"
))

remotes::install_github("brainworkup/cingulate")

quarto --version
# Expected: 1.4.x or higher
