Does anyone know of any resources to help me become more proficient in using rvest?
I've used rvest on and off ever since it was first released.
But I don't have a clue what I am doing, and always feel like whenever I'm able to get what I want from a webpage it's by as much by luck as by skill.
I usually just want to grab a table from wikipedia or all of the links from a page. Simple stuff.
But I don't really know where to start, I fiddle around with the SelectorGadget add-in to Chrome, and I have done things enough time to eventually get what I want.
And when I do get what I want, I get frustrated with the data structures - what methods are useful here?
Assume I know nothing except tidyverse. Do I need to learn some html? Do I need to know what an xpath is? The rvest documentation is useful but I feel like I'm missing step 0 where I learn what everything is and how best to apply it.
