similarity test with R

x=c(3.05176E-05,0.000457764,0.003204346,0.0138855,0.04165649,0.09164429,0.1527405,0.1963806,0.1963806,0.1527405,0.09164429,0.04165649,0.0138855,0.003204346,0.000457764,3.05176E-05)
y=c(0.0000306,0.0004566,0.0031985,0.0139083,0.0415539,0.0917678,0.1528134,0.1962831,0.1962994,0.1527996,0.0917336,0.0415497,0.0139308,0.0031917,0.0004529,0.0000301)

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
