# Descriptive statistics and function masking

Previously, you have seen that the `summary()`

function computes the mean, median, 1st, and 3rd quartiles plus the min and max. The standard deviation is not included. However, the `Hmisc`

and `psych`

packages both have a `describe()`

function that provide more descriptive statistics including the standard deviation.

To get these descriptive statistics, you will run the `describe()`

function which has the same name in both packages. To avoid confusion, you should always use the notation `packagename::functionname()`

to explicitly specify the function from the package you want.

The `abaloneKeep`

dataset and `dplyr`

package are already loaded for you.

Instructions

**100 XP**

- Load
`Hmisc`

package - Get descriptive stats for abalone sex, length, diameter, and height using
`Hmisc::describe()`

function. - Load
`psych`

package - notice the warnings about the`describe()`

function masked from`Hmisc`

package*(since both packages have a*.`describe()`

function) - Run
`describe()`

function from`psych`

package to get descriptive stats for abalone length, diameter, height. Leave sex out since`psych::describe()`

only works for numeric variables.
