The first step would be to see if the error is reproducible just from
those few lines, so in R do
  data(USJudgeRatings)
  pairs(USJudgeRatings)
  cor.test(~ CONT + INTG, data = USJudgeRatings)

That's not likely, but it would be so much simpler than the alternative,
which is that some earlier command has corrupted some internal structure
in R.  In this more likely case it may be necessary to progressively
remove code from the test file until the bug goes away, to try to locate
it.
