Help explain how to do step by step scripts in R Studio:

Our task is to create a script that will analyze the 'presidents' dataset which is an R built$-$in dataset. This is what the script will do:

$1.$ Import the presidents data into a data frame called PresAp. The data is stored as a time series. Use the as$.$numeric$()$ function to store it into a data frame.

$2.$ Clean the data! $($Remove the NA from the data$)$ Hint: You can use the drop$\_$na$()$ function which is part of the tidyr package.

$3.$ Calculate the measures of Central Tendency $($mean$,$ median, and mode$)$ and store them into the following variables: PresMean, PresMedian, PresMode.

$4.$ Calculate the measures of variations $($Standard Deviation and Range$)$ and store them into the following variables: PresSd and PreRange

$5.$ Calculate the Z$-$scores for all the data points and add it to PresAP as a column called Zscores.

$6.$ Using the filter function $($which is part of the dplyr package$),$ display the outliers $($if any$).$

$7.$ Using the filter function, display all values that have a $\backslash ($ z $\backslash )$ score of $\backslash (>|2|\backslash )$
