First of all, we have to understand the nature of error. When you notice object type closure subsettable alerts, it has a problem originating from R – Python. 

R is a dedicated statistical programming language which works in sync with Python to help people make the best use of statistical analysis and data. Right now, R is an emerging language and will become one of the most popular languages in the next few years. 

As a learner, making use of R-base functionality can help. 

How to Fix Object of type ‘closure’ is not subsettable error?

R is a specialized programming language, which was especially designed and developed for performing statistical operations. But over the last few years, it has started gaining momentum for other uses as well. Academics and companies have started using this programming language for various other purposes as well. It’s 100% free, effective and accurate. 

As far as the object of type closure is not subsettable error is concerned, it may happen because of try to subset a function. 

You can subset matrices and vectors, but subsetting any function is not allowed. Especially when a function comes with a ‘closure’ you shouldn’t try to subset it. 

An Example of Such an Error

Suppose we want to process a function in R-language that multiplies each value by 3, we have; 

#Explain Chocolate 

Sweety_chocolate <-chocolate(x) {

X <- X*3

Return(X)

} 

The result means each data will be automatically multiplied by 3.

Error: object of type ‘closure’ is not subsettable: More Information

Another reason when you face error: object of type ‘closure’ is not subsettable is when you try to subset any standard deviation functionality.

How to Fix error in object[[i]] : object of type ‘closure’ is not subsettable?

The only way to make sure that you don’t face the error again is by not processing subsetting function. Another option you have is not to name a variable once R-functions got started. Never call variables as data. You have to make sure that both are demarcated properly and you can’t interchange them while using R. 

If you ever want to subset a function, you can try so using parenthesis. 

For example, take this example:

Books(shiny)

reactive_df <- reactive({

data.frame(col1 = c(1,2,3),

            col2 = c(4,5,6))

}) 

In Conclusion:

If you don’t want to get repeated alerts on this error, you have to start using brackets. You can use () sign—while pointing out to R object. For example; 

You can use the following code: 

RPythonDataLanguage()

Or

RPythonDataLanguage()$X 

Make sure variable names are in order. 

Don’t mix one variable to another. Each variable has a set of different work to perform. You can’t interchange one with another. Also, naming variables shouldn’t be as same as the one you opted for functions within the R base library. If you follow these steps and precautions properly, you may never come across Object of type closure is not subsettable error again while working on Python or R.
