Example data set please.
Using the TEXT variable, I want to delete all of the prepositions/conjunctions/auxiliary verbs. Below is an example of a string in the TEXT variable:
The cognitive functions of language and memory are compromised in the initial stages of Alzheimer’s disease (AD). Among the language tasks that are impaired in the initial stages of AD are the understanding of textual reading and lexical production. The difficulties in understanding textual reading in these patients are known to be attributed to cognitive flaws, such as those involving episodic memory, short term memory (working memory) and attention, found early in the disease. Reports from outline that the elderly without dementia remember more items of information than those with dementia. These studies show that the retelling of stories is an accurate procedure to discriminate the disease. On the other hand, lexical difficulties, verified through the naming of pictures, have been said to be due to flaws in the lexical access or to semantic memory flaws. As the studies about linguistics disturbances in patients with AD have focused on these two activities separately, little is known about how these lexical difficulties interfere in the retelling of stories.
