Cannot run a r package in python

Question

I want to use the R package 'grpreg'. However, I do not want to run it in R. Instead, I want to run the package under python. I have searched that I need to install the package rpy2, which allows me to run an R package under python. After installing rpy2, I enter

> `from rpy2.robjects.packages import importr`
> `base=importr('grpreg')`

Unfortunately, I obtain the error messages:

R[write to console]: Error: package or namespace load failed for 'grpreg' in inDL(x, as.logical(local), as.logical(now), ...):
 unable to load shared object 'C:/Program Files/R/R-4.1.3/library/stats/libs/x64/stats.dll':
  LoadLibrary failure:  The specified module could not be found.

  LoadLibrary failure:  The specified module could not be found.

Traceback (most recent call last):

I would like to know how to fix the problem.
