[R] Using "subset" in correlation analysis

The correlation test function says that it can do a subset where one specifies the subsete vector. I cannot seem to get it to work.

For example, the command line is:

cor.test(adults$Alt, adults$Cab, alternative="greater", method="pearson")

So, let´s say my subset vector is "Sex". How would I state the command to get the test of that subset?

Thanks in advance.

Jim
