quantmod, getSymbols, csv

Making a first attempt use quantmod's getSymbols to load data from a 
.csv file, I have encountered a puzzling error message.
The response to
getSymbols("CREFglobaleq", from="1992-05-01", to="2008-06-30", src="csv")
is
Error in fromchar(x) :
   character string is not in a standard unambiguous format

My basic problem is ignorance about what is acceptable as "a standard 
unambiguous format."  Explanations or references to documentation would 
be greatly appreciated.

The first few rows of my CREFglobaleq.csv file read as follows:
fund     ,  price  ,  date      ,  id
CREFglob , 25.8429 , 1992-05-01 , 199205
CREFglob , 25.9774 , 1992-05-04 , 199205
CREFglob , 25.9964 , 1992-05-05 , 199205   	
CREFglob , 26.2335 , 1992-05-06 , 199205
CREFglob , 26.3368 , 1992-05-07 , 199205

Best regards,
