Vectors in R programming is one of the most used or useful function. Vectors are considered as the basic data objects in the R language. If you don’t know, there are 6 types of Vectors are there –
- Logical vectors
- Integer Vector
- Double vector
- Character vector
- Complex vector
- Raw vector
What is a Vector in R programming?
A vector is an R language data object which contains a sequence of elements of the same data type. The elements in the vector are called as components.
The above is the basic example of the Vector in R programming. It has 5 elements in it i.e. 1,2,3,4 and 5.
Types of Vectors in R
As I mentioned earlier, there are 6 types of vectors are there in the R language. Let’s see each one of them with an example to get a good hold of those.
1. Vector with type Logical:
2.Vector with Type Character:
3.Vector with type Double:
4.Vector with type Integer:
5.Vector with type Complex:
6.Vector with type Raw:
68 65 79
Create Multi-Elemental vector in R
Yes, as the title suggest, you can easily create a vector which has multiple elements in it.
Let’s see how it works.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20
Let’s see another example – If the ending / final element does not match with the regular sequence then it can be neglected.
1.5 2.5 3.5 4.5 5.5
The above output shows that the given number (final value) is not matching the sequence and hence it is neglected.
Access elements in a vector
In this section, let’s see how we can access the elements present in the vector.
df<-c(13:23) df x<-df[c(2,4,6,8)] x
14 16 18 20
In the above vector, we have accessed the positions of 2,4,6 and 8. The function returned those values which we have requested to print.
Adding the vectors:
You can add the two vectors using the arithmetic operator of sum.
#creating vector vector_1 <-c(1,2,3,4) vector_2 <-c(6,7,8,9) #Adds the vectors vector_1+vector_2
7 9 11 13
Just like the above, you can create vectors, manipulate them and print them as well.
Wrapping Up – Vectors in R programming
Well, vectors are the R data objects which store the data in sequence and of the same data type.
There are 6 vector types and each of them is emplaned in the above sections with a reference of each individually.
I hope by now you will get a better idea about the vectors in R programming. That’s all for now. Happy Vectors!!!
