cor shows only NA or 1 for correlations - Why?

Question

I\'m running cor() on a data.framewith all numeric values and I\'m getting this as the result:

       price exprice...
price      1         


        

Answer 1

very simple and correct answer

Tell the correlation to ignore the NAs with use argument, e.g.:

cor(data$price, data$exprice, use = "complete.obs")
