R: Encode or Decode a (partial) URL

URLencode {utils} | R Documentation

## Encode or Decode a (partial) URL

### Description

Functions to encode or decode characters in URLs.

### Usage

    URLencode(URL, reserved = FALSE)
    URLdecode(URL)

### Arguments

`URL` | A character string.
`reserved` | should reserved characters be encoded? See ‘Details’.

### Details

Characters in a URL other than the English alphanumeric characters and `$ - _ . + ! * ' ( ) ,` should be encoded as `%` plus a two-digit hexadecimal representation, and any single-byte character can be so encoded. (Multi-byte characters are encoded as byte-by-byte.)

In addition, `; / ? : @ = &` are reserved characters, and should be encoded unless used in their reserved sense, which is scheme specific. The default in `URLencode` is to leave them alone, which is appropriate for `file://` URLs, but probably not for `http://` ones.

### Value

A character string.

    (y <- URLencode("a url with spaces and / and @"))
    URLdecode(y)
    (y <- URLencode("a url with spaces and / and @", reserved=TRUE))
    URLdecode(y)
    URLdecode("ab%20cd")
