I am new to R. I have a data like:
x y z w p .......... m
1 10 15 20 25 30
2 11 16 21 26 31
3 12 17 18 19 20
4 51 52 53 55 67
.......
thus I have 145 rows and 160 column in my data which is named as
data.csv. Now i want to create a new column 'm' and for every row m
will take value =column 7+ column 12+ column 57+ column 45 i.e. for
every row it will take value of sum of corresponding row's 7 & 12 & 57
& 45 column's value .
So, how to write the code for this operation?
