Installing R "pegas" package using rpy2

Question

I am trying to install the pegas R package using rpy2 but I am having trouble.

The error says 'The R package "pegas" is not installed'.

Could someone please direct me.

import rpy2
print(rpy2.__version__)

import rpy2.robjects as robjects

# import rpy2's package module
import rpy2.robjects.packages as rpackages

# R vector of strings
from rpy2.robjects.vectors import StrVector

# R package names
#Import R's pagas package
package_names = ('pegas')

if all(rpackages.isinstalled(x) for x in package_names):
    have_package = True
else:
    have_package = False
if not have_package:
    # import R's utility package
    utils = rpackages.importr('utils')

    # select a mirror for R packages
    utils.chooseCRANmirror(ind=1) # select the first mirror in the list

    # Selectively install what needs to be install.
    # We are fancy, just because we can.
    packnames_to_install = [x for x in package_names if not rpackages.isinstalled(x)]
    if len(packnames_to_install) > 0:
        utils.install_packages(StrVector(packnames_to_install))

pegas = rpackages.importr('pegas')
import rpy2.robjects.lib.pegas as pegas```
