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.

R For SAS Users
Exercise instructions
- Compute correlations between age, whole weight, shucked weight, shell weight, and viscera weight using
psych::corr.test()
. Save the output asabcorr
. - Display the
r
andp
elements from theabcorr
output to review the Pearson's correlation coefficients and associated p-values.
