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=",")

You can easily find and changed the data by using lookup table. You can also find the data within few seconds.
Answer:
public class Date{
Public Date(int month,int day,int year){
}
}
void main(){
Date datep=new Date(3,12,2006);
}
Explanation:
Here we declared a class "Date" and defined one public constructor which will take month,day and year. In main we created an object to that Date class by invoking this parameterized constructor and assigned that object to "dateap" Date variable
Complete Question:
The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.
Group of answer choices
a. Router
b. Switch
c. Bridge
d. Hub
Answer:
d. Hub.
Explanation:
A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.
<em>Hence, the main disadvantage of using a hub is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.</em>
