py_install(packages, envname = "r-reticulate", method = c("auto", "virtualenv", "conda"), conda = "auto", ...)
Character vector with package names to install

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.
Path to conda executable (or "auto" to find conda using the PATH and other conventional install locations).
On Linux and OS X the "virtualenv" method will be used by default ("conda" will be used if virtualenv isn't available). On Windows, the "conda" method is always used.
