I have created the data frame but the issue is with function. I am showing my code :

employee <- data.frame("Name","Gender","Age","Designation","SSN")
emp <- function(employee){
  Name <- as.character(readline("Enter name: "))
  Gender <- as.character(readline("Enter gender: "))
  Age <- as.integer(readline("Enter age: "))
  Designation <- as.character(readline("Enter designation: "))
  SSN <- as.integer(readline("Enter SSN: "))
}
return(emp)
emp()

View(employee)


I can not get my answer.

You can try something as given below: 

employee <- data.frame(Name = character(), Gender = character(),
                       Age = numeric(), Designation = character(),
                       SSN = numeric())

emp <- function(){
  Name <- as.character(readline("Enter name: "))
  Gender <- as.character(readline("Enter gender: "))
  Age <- as.integer(readline("Enter age: "))
  Designation <- as.character(readline("Enter designation: "))
  SSN <- as.integer(readline("Enter SSN: "))
  return(data.frame(Name, Gender, Age, Designation, SSN))
}

newentry <- emp()
employee <- rbind(employee, newentry)
View(employee)
