How to do it...

Perform the following steps to create and see vector in R:

> x=c(1,2,3,4) # c(1:4) 
> x 
Output: 
[1] 1 2 3 4 
> x=c(1,2,3,4,"ABC") 
> x 
Output: 
[1] "1" "2" "3" "4" "ABC" 
> x * 2 
Output: 
[1] 2 4 6 8 
> sqrt(x) 
Output: 
[1] 1.000000 1.414214 1.732051 2.000000 
> y = x==2 
> y 
Output: 
[1] FALSE TRUE FALSE FALSE 
> class(y) 
Output: 
[1] "logical" 
> t = c(1:10) 
> t 
Output: 
[1] 1 2 3 4 5 6 7 8 9 10
