In environment.yml:

dependencies:
  - r-base
  - r-r.utils
  - rpy2
  # (other r packages)

Imports:

import numpy as np
import rpy2.robjects.packages as rpackages
from rpy2 import robjects
from rpy2.robjects import numpy2ri

Import R modules:

base = rpackages.importr("base")
stats = rpackages.importr("stats")

Install and load package:

utils = rpackages.importr("utils")
utils.chooseCRANmirror(ind=1)

utils.install_packages("condMVNorm")
condMVNorm = rpackages.importr("condMVNorm")

Begin:

numpy2ri.activate()

Make vector:

vec1 = np.array([1.2, 2.5, 3.3])
vec1_r = robjects.FloatVector(vec1)

vec2 = np.array([1, 2, 3])
vec2_r = robjects.IntVector(vec2)

Make matrix:

mat = np.arange(1, 10).reshape(3, 3)
mat_r = base.matrix(mat, 3, 3)

End:

numpy2ri.deactivate()
