   2 x = [1,2,3,4,5,6,7,8,9,10]
   3 y = [2,2,3,3,4,4]
   4 result = r.t_test(x,y)
   5 print result['p.value']

• F-Test

   1 from rpy import *
   2 x = [1,2,3,4,5,6,7,8,9,10]
   3 y = [2,2,3,3,4,4]
   4 result = r.var_test(x,y,alternative='greater') # alternative가 없으면 default로 two-sided test가 된다.
   5 print result['p.value']
