When I just run a for loop it works. But if I am going to run a for loop
every time for large vectors I might as well use C or any other language.
The reason R is powerful is becasue it can handle large vectors without each
element being manipulated? Please let me know where I am wrong.

for(i in 1:length(news1o)){
+ if(news1o[i]>s2o[i])
+ s[i]<-1
+ else
+ s[i]<--1
+ }
