$ Operator is invalid for atomic vectors

R and PHP both are programming languages that get popularity in the world of programming. Those are widely used by a huge number of data scientists and programmers for some years. R programing language is developed after many testing. It gives errors notification which huge description which is sometimes not easy to understand for beginners and people. In basic R programing language, one of the most occurred errors is “$ operator is invalid for atomic vectors”.

If you have to go through this error and do not know what to do then you do not need to be worried about it. In this article, you will find out everything about this issue and the solution to this error.

So, if you want to fix this error then you need to read this article carefully. So, let us start our discussion about the $ operator being invalid for atomic vectors.

What is Error “$ operator is invalid for atomic vectors”?

This is a common error in the programing language R. this error appears when you try to access an element of an atomic vector with the $ operator. An “atomic vector” is any dimension in a data structure developed by using the c () or vector () in the R programing language.

People faced a common error when they are operating their data structures with R programing language. When people face this error in R language then they get worried that how to deal with error because the notification of this error is very brief which is sometimes un-understandable for people.

What is an atomic vector in R Programing Language?

R is one of the most popular programming languages. This programing language is used by many data scientists and programmers but sometimes an error occurs in the R which is “$ operator is invalid for atomic vectors”. This error commonly occurred due to the effort to get access to an element of the atomic vector.

The atomic vector is certainly the most central data structure in the R programing language. An atomic vector is very dissimilar from a dimensional array. An array contains a blurred quality of length whereas a vector does not show such characteristics.

Background of R Error

$ Operator is invalid for atomic vectors are the most common error in R language. When programmers and data scientists are using R programming, they need more concentration because there might be a chance to occur an error.

The error happened when programmers try to utilize an element of an atomic vector with the $ operator. Here, I am using a world character vector for the atomic vector because they are aware of this name. The atomic vector has two types’ logical atomic vector and integral atomic vector. Here, I mentioned an example to clarify your concept.

#Numeric Vector 

NumVec< – C (3, 2.5, 5.6) 

# Character Vector 

CharVec < – C(“Hello”, “GroupA”) 

# Integer Vector 

IntVec < – 

C (2L, 4L, 11L) 

# Logical Vector 

LogicalVec < – c (TRUE, FALSE, T, F)

You can understand the types of atomic vectors in R by the example mentioned above. If you want to check whether the vector is atomic or not then you need to apply “is. atomic (numVec)”. It gives “TRUE” if the vector is atomic otherwise it shows “FALSE.”

When R Error might arise?

R is a new programing language, which is introduced a few years in the programming world. Programmers and data scientists think this programing language is reliable and use this in their data structures or programming. However, this programing language has a common error, which is $ operator is invalid for atomic vectors.

The error occurred when the programmer or R operator tries to approach the element of the atomic vector using the $ operator. When this error occurred in the R programing language then a notification appeared on the screen, which is “$ operator is invalid for atomic vectors”.

When you are doing programming using the R programing language and a notification appears on your screen telling you, it means that the error occurred in your programming.

Methods to fix the error R

The error “$ operator is invalid for atomic vectors” is also known as an R error is a common error that occurred in the programing language R. When this error occurred then you do not need to be worried because it is not too difficult to resolve this error.

So, if you faced the error “$ operator is invalid for atomic vectors” during R programming then you have three ways by which you can easily resolve the issue.

Methods to fix the error R

The three ways by which you can resolve the error with methods are mentioned below:

  1. Apply Double Brackets
  2. Apply GetElement
  3. Conversion in Dataform

You can use all the above solutions to resolve the error “$ operator is invalid for atomic vectors”. If sometimes, during your work this error occur then you do not need to be worried. The description to use the above three solutions to resolve the error is given below:


  1. Use Double Brackets

When the error “$ operator is invalid for atomic vectors” occur, you can resolve it easily by using a double bracket in the data structure.

The error commonly occurred when you try to get access to an element of the atomic vector. We can resolve the error “$ operator is invalid for atomic vectors” by using the Double bracket.

Do not try to approach the element of the atomic vector directly. Use double brackets to get access to the element of atomic vectors to avoid this error. Ensure the use of quotes in the name because it is a string to make the data structure reliable and efficient.

numVec [[‘A’]] 

[1] 3 

This is the best and quick solution to avoid or resolve the error.

Why cannot use a single bracket?

We can use a single bracket to do this however; the output will be in a different format. It provides name numbers except for numbers. Such as,

numVec [‘A’]

It does not give a name. It just gives numbers by which we cannot process it more. Therefore, it is good to use double brackets as compared to single brackets. Using a single bracket makes things complex.

Therefore, if you want to resolve the error in the R language then you should use a double bracket instead of a single.


  1. Use getElement ()

getElement is another way by which we can resolve the error. getElement () consist of syntax style such as “getElement(Object, name). It is designed to resolve this sort of issue in R programming. Therefore, you can use getElement by using the following method:

GetElement (numVec, ‘A’)

[1] 3

It is also easy to process. Therefore, if you are looking for an easy way by which you can resolve the error then this method is easy for you.


  1. Conversion to DataFrame

This is not a suggested way but it is used as a last option. When you try out the above methods but cannot resolve the error “$ operator is invalid for atomic vectors” then this is another method to resolve the error “$ operator is invalid for atomic vectors”.

You can resolve this error in R programming by using the “data.frame ()”. If you want to use a data frame then you need first to transfer the vector before converting it into a data frame. You need to save the data in a one-row vector name. If you want to use this method then you can use it by following the method below:

myDF <- data.frame (t(numVec))

myDF$A 

[1] 3 

It is an easy method to resolve the issue. So, if you want to get rid of the error $ operator is invalid for atomic vectors or avoid this error then you can use this way for this purpose.

What is the Dollar sign “$” operator in R programming?

The dollar sign is a component in R programming. You can use this sign operator to select a variable, give new values, and add new values to an R Object. This sign operator is only suitable for the recursive object in R programming.

When we try to approach an element of the atomic vector using the $ sign an error occurred which is “$ operator is invalid for atomic vectors”.

Final Words

R programming language is the popular and widely used programing language these days. However, an error occurred commonly in this programing language. This error occurred when the operator or programmers try to approach an element of an atomic vector by applying the $ operator.

When they get this error then they get confused about how to resolve the issue. This article enables you to resolve the issue. If you want to deal with the error “$ operator is invalid for atomic vectors” then you can do by following the ways mentioned here. I hope at the end of this discussion it.
