The data set at $$rainfall$\_60-79.$dat$$ records hourly rainfall at a certain location in Canada, from $1960$ to $1979.$

First, we need to load the data set into R using the function read.table$().$ Use the help function to learn how to use this function read.table$().$ Load the data set into R and make it a data frame called canada$\_$rain$\_$df$.$

How many rows and columns does canada$\_$rain$\_$df have? $($If there are not $4826$ rows and $27$ columns, something is wrong; check the previous part to see what might have gone wrong.$)$

What is the value of $($row $3,$ column $3)$ in canada$\_$rain$\_$df$?$

Display the third row of canada$\_$rain$\_$df in its entirety.

Explain what this command does:

names$($canada$\_$rain$\_$df$)<-$ c$("$year$",$"month","day",seq$(0,23))$

by running it on your data and examining the object. $($You may find the display functions head$()$ and tail$()$ useful here.$)$ Is it clear now what the last $24$ columns represent?

Create a new column in the data frame called daily, which is the sum of the rightmost $24$ columns. With this column, create a histogram of the values in this column. This new column is supposed to contain daily rainfall values. What is wrong with this picture? Check the data to discover the problem.
