[R-sig-eco] report out by t.test

[Michael Marsh]

I test differences between frequency of hits of exotic annual forbs in 
plots on  two sites, Q and WD.

 > Q<-c(13,0,10,2,0,0,1,0,0,1,5)
 > WD<-c(0,0,1,0,0,0,0,0,0,0,1)
 > t.test(Q,WD)

         Welch Two Sample t-test

data:  Q and WD
t = 1.9807, df = 10.158, p-value = 0.07533
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
  -0.3342006  5.7887460
sample estimates:
mean of x mean of y
2.9090909 0.1818182

The p-value is greater than 0.05, thus does not reach the 95% confidence 
level, yet the difference in means is reported as not equal to 0.
Am I encountering a one-sided versus two sided comparison that I don't 
understand, or is ther another explanation?
