As the semester progresses, we will work more with R$,$ a statistical programming

language. To get you started using R$,$ write a short R code that does the following:

$($a$)$ Read the excel file into R studio. Hint, you need to load a package, and I

suggest you read in the un$-$edited Excel file. $[1$ point$]$

$3$

$($b$)$ Filter the data frame to include only lakes from Cape Breton County. Hint:

you will need to load another package. $[1$ point$]$

$($c$)$ Calculate the median and interquartile rage of mean depth of all lakes in Cape

Breton County. Report the numbers here. $[2$ points$]$
