In "file.copy" R function,
what mean "recursive" in "overwrite" argument default value ?

> args(file.copy)
function (from, to, overwrite = recursive, recursive = FALSE,  
    copy.mode = TRUE, copy.date = FALSE)

>Solution :

That means overwrite will use the value of recursive by default. Since recursive is false by default, overwrite will be false if both are left unspecified. If you change recursive to true and leave overwrite unspecified, it will also become true. It’s just telling you where the default value is coming from.
