How to deal with the NA results in corr.test using log2(x+1)?

Question

Here is my question before:C: which kind of normalization is suitable for corr.test has been already finished.

Now I met a new problem with my result after I used corr.test with log2(fpkm+1) gene expression counts. That means I got many NAs after filter :

res<-res[abs(res$r)>0.65 & res$p<0.05,]

> res<-res[abs(res$r)>0.65 & res$p<0.05,]
> res

NA.19           NA           NA
NA.20           NA           NA

Is there anything wrong? Should I think that I can filter the NAs only ? Is't that right with NAs in my corr.test(log2(fpkm+1)) results ?

I need your help. Vary thankful.
