Installation

The topics package relies on Java for high-performance processing. To ensure a smooth installation, please follow these two steps.

Step 1: Install Java (Required)

Before installing the R package, you must have the Java Runtime Environment (JRE) installed on your computer. 1. Download Java from here or www.java.com/en/download/. 2. Restart your computer after installation to ensure R can detect the new system paths.

Step 2: Install topics in R

Open R or RStudio and run the following commands.

# Install and verify the Java interface
install.packages("topics")

You can also install the development version from GitHub.


# Install devtools if not already present
if (!requireNamespace("devtools", quietly = TRUE)) install.packages("devtools")

# Install topics from GitHub
devtools::install_github("theharmonylab/topics")

Step 3: Memory Configuration

Topic modeling is memory-intensive. You must increase the Java memory limit before loading the library. If you skip this, you may encounter OutOfMemoryError during model training.

# Set memory limit to 5GB (Run this BEFORE loading the library)
options(java.parameters = "-Xmx5000m")
library(topics)
