[R] example - export a data frame to an XML file

[zubin]

Duncan, thanks for the note - the schema looks like this - is this what 
your asking for?

<document>
 <row>
  <date>2007-02-01</date >
  <UYG_Open>71.32</UYG_Open >
  <UYG_High>71.34</UYG_High >
  <UYG_Low>71.32</UYG_Low >
  <UYG_Close>71.34</UYG_Close >
  <UYG_Volume>200</UYG_Volume >
  <UYG_Adjusted>69.23</UYG_Adjusted >
 </row>
 <row>
  <date>2007-02-02</date >
  <UYG_Open>72.2</UYG_Open >
  <UYG_High>72.2</UYG_High >
  <UYG_Low>72.2</UYG_Low >
  <UYG_Close>72.2</UYG_Close >
  <UYG_Volume>200</UYG_Volume >
  <UYG_Adjusted>70.06</UYG_Adjusted >
 </row>
