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: 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.
