Systematic Literature Review using litsearchr
K Wolcott
26 Dec 2023
Introduction
Use this notebook to carry out a systematic literature search using litsearchr on a Mac OS. We are investigating the morphology and evolution of the Byttnerioideae, a taxonomically challenging clade within the Malvaceae. First, you will use some manually selected keywords for preliminary searches. Then, keywords will be automatically extracted from the abstracts found during the preliminary passes. Finally, carry out a systematic literature search using the complete list of keywords and analyze patterns in found articles.
These steps were made following a tutorial from https://www.r-bloggers.com/2023/03/automated-systematic-literature-search-using-r-litsearchr-and-google-scholar-web-scraping/
