Hi Shahab, This test shows that there is some positive statistical correlation, BUT the p-value of the test - this is, the level of significance - shows that the correlation is not statistically significant at 95% confidence level. So, the correlation may be equal to zero.
To understand this concepts in a good way, you need to be secure about variance and hypothesis test. I can help you more if you need. Send me a direct mail (this list is for doubts about R, not conceptual statistics). I will be happy to help you with Statistics.
