Most text analysis can be performed in R using the tidytext package. Below are two open-source books that provide an excellent overview of general text analyses in R:
Link to Text mining for Social Scientists by Felix Lennert
Link to Text Mining with R by Julia Silge and David Robinson
You can also set up an appointment with Dr. Tommy Patterson if you are interested in learning more about how text analysis can be incorporated into your research
