Install RKeOps requirements — install

Install requirements (i.e. Python packages) for RKeOps to work.

Usage

install_rkeops(
  envname = NULL,
  method = c("auto", "virtualenv", "conda"),
  conda = "auto",
  python_version = NULL,
  pip = FALSE,
  ...,
  pip_ignore_installed = ignore_installed,
  ignore_installed = FALSE
)

Arguments

envname: The name, or full path, of the environment in which Python packages are to be installed. When NULL (the default), the active environment as set by the RETICULATE_PYTHON_ENV variable will be used; if that is unset, then the r-reticulate environment will be used.
method: Installation method. By default, "auto" automatically finds a method that will work in the local environment. Change the default to force a specific installation method. Note that the "virtualenv" method is not available on Windows.
conda: The path to a conda executable. Use "auto" to allow reticulate to automatically find an appropriate conda binary. See Finding Conda and conda_binary() for more details.
python_version: The requested Python version. Ignored when attempting to install with a Python virtual environment.
pip: Boolean; use pip for package installation? This is only relevant when Conda environments are used, as otherwise packages will be installed from the Conda repositories.
...: Additional arguments passed to conda_install() or virtualenv_install().
pip_ignore_installed, ignore_installed: Boolean; whether pip should ignore previously installed versions of the requested packages. Setting this to TRUE causes pip to install the latest versions of all dependencies into the requested environment. This ensure that no dependencies are satisfied by a package that exists either in the site library or was previously installed from a different--potentially incompatible--distribution channel. (ignore_installed is an alias for pip_ignore_installed, pip_ignore_installed takes precedence).

Details

RKeOps now uses PyKeOps Python package under the hood thanks to the reticulate R package that provides an "R Interface to Python".

We recommend to use a dedicated Python environment (through reticulate) to install and use RKeOps Python dependencies.

install_rkeops() is just a wrapper around reticulate::py_install() and takes the same input arguments.

See the specific "Using RKeOps" article or the corresponding vignette: vignette("using_rkeops", package = "rkeops")

Important: Python is a requirement as an intern machinery for the package to work but you will not need to create nor manipulate Python codes to use the RKeOps package.

Examples

if (FALSE) {
## setup Python virtual environment
# create Python virtualenv
reticulate::virtualenv_create("rkeops")
# activate python environment
reticulate::use_virtualenv(virtualenv = "rkeops", required = TRUE)

## install rkeops requirements in Python virtual environment
install_rkeops()

## check install
check_rkeops()
}
