How to create vector in R with a sequence of numbers?
Creating a numeric vector is the first step towards learning R programming and there are many ways to do that but if we want to generate a sequence of number then it is a bit different thing, not totally different. We can create a vector with a sequence of numbers by using − if the sequence of numbers needs to have only the difference of 1, otherwise seq function can be used.
Example
> x1<-1:50 > x1
Output
[1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 [26] 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
Example
> x2<-50:1 > x2
Output
[1] 50 49 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 [26] 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1
Example
> x3<-seq(1,100,by=5) > x3
Output
[1] 1 6 11 16 21 26 31 36 41 46 51 56 61 66 71 76 81 86 91 96
Example
> x4<-seq(1,500,by=5) > x4
Output
