The best place to learn more about changing variable types is Chapter 20 of R for Data Science. Be warned that the chapter is dense, but it goes over, in greater depth, various variable (technically, vector) types, how to change them, etc.

I changed some of my variables to numeric in order to run a correlation test, but when I attempt to run cor.test, I get the error message that "'x' must be a numeric vector" even though both x and y are reading as dbl variables. My code is here: https://github.com/herlafrance/NBV_HRL2022RCourse/blob/master/VSA_2022_HRL_NBV_ongoing_project.Rmd with the issues in question occurring from lines 195-222. I'm wondering if there's something going on with na values? Not sure what the remaining roadblock is.
