I am working with some XML data in R and running into errors regarding type 'externalptr'.

1) I get the following error when I try to use the xmlInternalTreeParse() function (part of XML package).

 doc = xmlInternalTreeParse(xmldatavariable)
    'Error in as.vector(x, "character") : cannot coerce type 'externalptr'
 to vector of type 'character''

2) I get this error when I try to write the XML data to a text file so I can look at it and see what the error might be.

write(xmldatavariable,"sample.txt")
Error in cat(list(...), file, sep, fill, labels, append) : 
      argument 1 (type 'externalptr') cannot be handled by 'cat'

Any suggestions? Thanks - Z
