### Explicit Coercion

Objects can be explicitly coerced from one class to another. See the below examples. x<- 1:10
class(x)
as.numeric(x)
as.logical(x)
as.character(x)

Output:

> x<- 1:10
> class(x)
 “integer”
> as.numeric(x)
 1 2 3 4 5 6 7 8 9 10
> as.logical(x)
 TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE TRUE
> as.character(x)
 “1” “2” “3” “4” “5” “6” “7” “8” “9” “10”

Sometimes, R also don’t how to coerce an object and this can result in NAs being produced. `x <- c("Statistics", "R Programming", "Python")as.numeric(x)as.logical(x)`

Output:

`>as.numeric(x) NA NA NAWarning message:NAs introduced by coercion > as.logical(x) NA NA NA`

Frequently you may wish to create a vector based on a sequence of numbers. The quickest and easiest way to do this is with the : operator, which creates a sequence of integers between two specified integers. y<-1:10
print(y)

Output:

> print(y)
 1 2 3 4 5 6 7 8 9 10

If we want to create a sequence that isn’t limited to integers and increasing by 2 at a time, we can use the seq() function. seq(from = 1, to = 10, by = 2)
seq(1.5, 10.2, 2)

Output:

 1.5 3.5 5.5 7.5 9.5

Another common operation to create a vector is rep(), which can repeat a single value a number of times. `rep("Statistics", times = 10)x<-c("Statistics","R Programming","Python")rep(x, times = 3)length(x)`

Output:

` "Statistics" "Statistics" "Statistics" "Statistics" "Statistics" "Statistics" "Statistics" "Statistics" "Statistics" "Statistics">> x<-c("Statistics","R Programming","Python")> rep(x, times = 3) "Statistics" "R Programming" "Python" "Statistics" "R Programming" "Python" "Statistics" "R Programming" "Python"> length(x) 3`
