login_gmql {RGMQL} | R Documentation

## Login to GMQL

### Description

Login to GMQL REST services suite as a registered user, specifying username and password, or as guest, using the proper GMQL web service available on a remote server

### Usage

    login_gmql(url, username = NULL, password = NULL)

### Arguments

`url` | string url of server: It must contain the server address and base url; service name is added automatically
`username` | string name used during signup
`password` | string password used during signup

### Details

If both username and password are missing, you will be logged as guest. After login you will receive an authentication token. As token remains valid on server (until the next login / registration or logout), a user can safely use a token for a previous session as a convenience; this token is saved in R Global environment to perform subsequent REST call even on complete R restart (if the environment has been saved). If error occurs, a specific error is printed

### Value

None

### Examples

    ## Login to GMQL REST services suite as guest

    remote_url = "http://www.gmql.eu/gmql-rest/"
    login_gmql(remote_url)
