using python virtual env in r

The Anaconda package manager conda supports creating R environments.

conda create - n r - environment r - essentials r - base
conda activate r - environment

To create desired environment -> "r_environment_name"

C: \ > conda create - n "r_environment_name"
r - essentials r - base

To see available environments

C: \ > conda info--envs

To activate environment

C: \ > conda activate "r_environment_name"

(r_environment_name) C: \ >

To install roveR, execute the following command in R:

install.packages("rover", repos = c("https://lair.functionalfinances.com/repos/shared", "https://lair.functionalfinances.com/repos/cran"))

R functions for managing Python virtual environments.,Virtual environments are by default located at ~/.virtualenvs (accessed with the virtualenv_root() function). You can change the default location by defining the WORKON_HOME environment variable.,The version of Python to be used with the newly-created virtual environment. Python installations as installed via install_python() will be used.,The Python module to be used when creating the virtual environment -- typically, virtualenv or venv. When NULL (the default), venv will be used if available with Python >= 3.6; otherwise, the virtualenv module will be used.

virtualenv_create(
   envname = NULL,
   python = NULL,
   ...,
   version = NULL,
   packages = "numpy",
   module = getOption("reticulate.virtualenv.module"),
   system_site_packages = getOption("reticulate.virtualenv.system_site_packages",
      default = FALSE),
   pip_version = getOption("reticulate.virtualenv.pip_version",
      default = NULL),
   setuptools_version = getOption("reticulate.virtualenv.setuptools_version",
      default =
      NULL),
   extra = getOption("reticulate.virtualenv.extra",
      default = NULL)
)

virtualenv_install(
   envname = NULL,
   packages,
   ignore_installed = FALSE,
   pip_options = character(),
   ...
)

virtualenv_remove(envname = NULL, packages = NULL, confirm = interactive())

virtualenv_list()

virtualenv_root()

virtualenv_python(envname = NULL)

virtualenv_exists(envname = NULL)

virtualenv is used to manage Python packages for different projects. Using virtualenv allows you to avoid installing Python packages globally which could break system tools or other projects. You can install virtualenv using pip.,This guide discusses how to install packages using pip and a virtual environment manager: either venv for Python 3 or virtualenv for Python 2. These are the lowest-level tools for managing Python packages and are recommended if higher-level tools do not suit your needs.,As long as your virtual environment is activated pip will install packages into that specific environment and you’ll be able to import and use packages in your Python application.,This doc uses the term package to refer to a Distribution Package which is different from an Import Package that which is used to import modules in your Python source code.
