Correlations output
In chapter 3, you computed the correlations between age and the four weight measurements using psych::corr.test(). However, the results were only displayed to the console.
In this exercise, you will save the output to an object named abcorr and then extract specific elements from that output including the p-values, so that you can display them with greater precision.
The abaloneKeep dataset, dplyr and psych packages have been loaded for you.
