browseURL
Displays the contents of a URL in a Web Browser

### Description

Displays in a web browser the contents found at a URL or the contents of a file or folder.

### Usage

    browseURL(url, browser = getOption("browser"), encodeIfNeeded = FALSE)

### Arguments

url | a character string. Usually it is a file path or a URL. Cannot be empty.
browser | the browser location. Must be either a character string, a function, or (on Windows only) NULL.
encodeIfNeeded | a logical flag: If TRUE, encode url. The default is FALSE.

### Details

Opens the specified browser or the default browser and displays the specified URL.

- If browser is a function, it is called by browseURL, and url is passed as an argument to the function.
- If browser is a populated character string, it is treated as the path to the browser executable and is started by the system function, passing url on the command line.
- If browser is NULL, the operating sytem launches the default browser to display url. (This option is supported only on Windows systems.)

Value

- If browser is a function, browseURL invisibly returns the function's result.
- if browser is a character string, browseURL returns 0 if the command ran successfully.
- if browser is a character string, browseURL returns 1 if the command failed to run.
- If browser is NULL, browseURL returns NULL.

Differences between Spotfire Enterprise Runtime for R and Open-source R
In open-source R, when browser is not NULL, the function "browseURL" fails to run.
