Запрос SOAP в R - программирование

Кто-нибудь знает, как сформулировать следующий запрос SOAP с помощью R?

POST /API/v201010/AdvertiserService.asmx HTTP/1.1
Host: advertising.criteo.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "https://advertising.criteo.com/API/v201010/clientLogin"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <clientLogin xmlns="https://advertising.criteo.com/API/v201010">
      <username>string</username>
      <password>string</password>
      <source>string</source>
    </clientLogin>
  </soap:Body>
</soap:Envelope>

library(RCurl) headerFields = c(Accept = "text/xml", Accept = "multipart/*", 'Content-Type' = "text/xml; charset=utf-8", SOAPAction = "https://advertising.criteo.com/API/v201010/clientLogin") body = '<?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body> <clientLogin xmlns="https://advertising.criteo.com/API/v201010"> <username>string</username> <password>string</password> <source>string</source> </clientLogin> </soap:Body> </soap:Envelope>' curlPerform(url = "https://advertising.criteo.com/API/v201010/AdvertiserService.asmx", httpheader = headerFields, postfields = body )
