The programing language, R has a unite unite function in the tidyr package. Hence, the code chunk which let's the analyst create the location column is; <em>unite (stores, "location”, city, state, sep=",") </em>
- The syntax for the unite function is ; unite(data,col,..., sep)
- <em>data</em><em> </em><em>=</em><em> </em><em>dataframe</em><em> </em><em>from</em><em> </em><em>which</em><em> </em><em>data</em><em> </em><em>is</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>extracted</em><em> </em><em>`</em><em>;</em><em> </em>stores
- <em>col</em><em> </em><em>=</em><em> </em><em>name</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>new</em><em> </em><em>column</em><em> </em><em>;</em><em>"</em><em> </em>location"
- <em>.</em><em>.</em><em>.</em><em> </em><em>=</em><em> </em><em>dataframes</em><em> </em><em>to</em><em> </em><em>be</em><em> </em><em>merged</em><em> </em><em>;</em><em> </em>city, state
- <em>sep</em><em> </em><em>=</em><em> </em><em>seperator</em><em> </em><em>;</em><em> </em>","
Hence, the required syntax goes thus :
- unite (stores, "location”, city, state, sep=",")

Answer:
The main advantage of using the linked implementation over the array implementation are:
- In linked list, the size of list does not need to be mention initially in the program in dynamic memory deallocation and allocation.
- We can easily add new elements and nodes in the linked list as there is no size limit.
- We can easily insert and also remove the elements and nodes in the linked list without re-organize the complete structure. As, the information do not need to be stored in the memory. On the other hand, array implementation takes maximum time as compared to linked list.
