Sentences with co-occurrence of two terms will be extracted along with the corresponding PMIDs. The output will be a data frame. In regard to the argument n, when the value is 0 then the co-occurrence is sought in the same sentence. When the value is 1, then the co-occurrence is sought in two consecutive sentences, namely, first term in the first sentence and second term in the next sentence. When the value is 2, then the co-occurrence is sought in two sentences separated by a sentence without either term1 or term2.
