I think it would be significantly more useful if we can have a case-study-like tutorial/walkthrough so everyone can see your analysis method and conclusion. Btw, I learned some new things from this video too nevertheless, thanks!!
It has been a while since I last used R Studio, so I watched this a a refresher. It was super helpful. Just wondering if you have a walkthrough of a dataset that include a categorial variable.
get error on : cor.test(df,use="complete.obs",methods="pearson",adjust="bonferroni") Error in cor.test.default(df, use = "complete.obs", methods = "pearson", : 'x' must be a numeric vector
Check the variables being correlated to make sure they are not factor or character variables. Your variables should be integer or numeric. You can use the str() function to see what types of variables you are correlating.
