Installs a list of packages into a specified conda environment

Usage

conda_install(
  envname = NULL,
  packages,
  forge = TRUE,
  channel = character(),
  pip = FALSE,
  pip_options = character(),
  pip_ignore_installed = FALSE,
  conda = "auto",
  python_version = NULL,
  ...
)

Arguments

envname: The name of, or path to, a conda environment.
packages: A character vector, indicating package names which should be installed or removed. Use <package>==<version> to request the installation of a specific version of a package. A NULL value for conda_remove() will be interpretted to "--all", removing the entire environment.
forge: Boolean; include the conda-forge repository?
channel: An optional character vector of conda channels to include. When specified, the forge argument is ignored. If you need to specify multiple channels, including the conda forge, you can use c("conda-forge", <other channels>).
pip: Boolean; use pip for package installation? By default, packages are installed from the active conda channels.
pip_options: An optional character vector of additional command line arguments to be passed to pip. Only relevant when pip = TRUE.
pip_ignore_installed: Ignore already-installed versions when using pip? (defaults to FALSE). Set this to TRUE so that specific package versions can be installed even if they are downgrades. The FALSE option is useful for situations where you don't want a pip install to attempt an overwrite of a conda binary package (e.g. SciPy on Windows which is very difficult to install via pip due to compilation requirements).
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 version of Python to be installed. Set this if you'd like to change the version of Python associated with a particular conda environment.
...: Optional arguments, reserved for future expansion.
