Installation

The easiest way to install repsim is through official repositories such as PyPI and CRAN.

Python

pip install -U repsim

R

install.packages("repsim")

The development version can also be installed from source hosted on GitHub:

Python

pip install git+https://github.com/kisungyou/repsim.git#subdirectory=repsim-Python

R

remotes::install_github("kisungyou/repsim", subdir = "repsim-R")

Dependencies

repsim is built on a shared C++17 computational backend, ensuring consistent performance across Python and R. To install and use repsim, your system should have

• A C++17-compatible compiler (e.g., GCC ≥ 9, Clang ≥ 10, or MSVC ≥ 2019)
• CMake ≥ 3.20 (required only when building from source)
• Standard build tools available on Linux, macOS, and Windows

For language-specific requirements, see below:

Python

Requires a modern Python environment (≥ 3.8) and the following build dependencies:

• scikit-build-core ≥ 0.10 - build backend integrating CMake with PEP 517
• pybind11 ≥ 2.11 -Python/C++ interface
• numpy ≥ 1.23 - array and numerical operations
• packaging ≥ 23.0 - version and metadata management

R

Requires R ≥ 4.2 and a working C++17 toolchain. All necessary C++ headers (Rcpp, Eigen) are bundled and linked automatically and no additional R dependencies need to be installed manually.
