Recalling r function in python using rpy2 reports *rpy2.rinterface_lib.embedded.RRuntimeError*

Question

You may have to install R-package as https://cran.r-project.org/web/packages/Rssa/index.html .

Below, I am confused on that only the last line reports error as "rpy2.rinterface_lib.embedded.RRuntimeError: Error in residuals - .get.series(x, rcached) : non-numeric argument to binary operator "

import rpy2
import rpy2.robjects as robjects
from rpy2.robjects.packages import importr
import rpy2.robjects.numpy2ri
rpy2.robjects.numpy2ri.activate()

rssa = importr('Rssa')
x = [i for i in range(300)]
s = rssa.ssa(x, L=100, kind = "1d-ssa")
r = rssa.reconstruct(s)
