I can use the following code to change the name in the cells in my data.frame:

df$column <- gsub("Old name", "New name", df$column)

However, I want to create it as a function. I have tried with the following, but it does not work:

changename <- function(data) {
  data$column <- gsub("Old name", "New name", data$column)
}

changename(df)

What do I do wrong?

Add `return(data)` in function? – Ronak Shah Nov 21 '20 at 08:35

`R` is call-by-value, that means that by calling your function, the operations in your function are performed on a local copy and not the original object – starja Nov 21 '20 at 08:36
Of course. My mistake. Thanks for your answer. :-) – Michael Nov 21 '20 at 08:45
