I tried chisq.test, t-test, prop.test, etc, but the p-value is very
high, which is not 'statistically significant'.  With these data sets,
I want to compare the similarity, which it is very close to identical
if you plot them.    I am wondering if there is any test that can
verify the similarity of the two data sets.

thx much
