How to return JSON using plumber api in R

Question

I am new to R . I am supposed to expose rest service using R , So i found plumber to expose rest service using R , I Successfully implemented plumber in R , but in response i am receiving a json array like below

[{"name":"Rajesh","age":"10"}]

how to remove the array from the above response

my expected output is like below

{"name":"Rajesh","age":"10"}

Code

 library(plumber)
r <- plumb("MyFile.R")
r$run(port=8000)

My File .R is mentioned below

    #* @post /sum
addTwo <- function(){
  name<-c("Rajesh")
  age<-c("10")
  df<-data.frame(name,age)

  return(df)

}

Plumber output serialization with json is documented in https://www.rplumber.io/articles/rendering-output.html — Holger Brandl, Mar 31 '22 at 06:10

`auto_unbox` argument is inside the wrong bracket, and I don't think this answers the question – SymbolixAU Mar 02 '17 at 03:57
you're probably right. i'll know more by this evening. – Eoghan Hynes Mar 02 '17 at 11:29
Seems, there was no final answer posted. @Rajesh did you figure out yourself? If yes could you care to close this question with the solution as I have the same question too? Thanks. – Lazarus Thurston Jun 30 '17 at 08:20
