Hello, have an XTS object, simply trying to save, but when i open the 
saved file and review the XTS object, its different, and most of the 
data does not exist.  How does one save an XTS object correctly?

Found this link but no mention;

example:  XTS object called VDF
 > str(vdf)
An 'xts' object from 2009-10-16 09:30:02 to 2009-10-16 15:59:56 containing:
  Data: num [1:2919, 1:9] 87.3 87.2 87.2 87.2 87.2 ...
 - attr(*, "dimnames")=List of 2
  ..$ : NULL
  ..$ : chr [1:9] "FAS" "VIX" "UUP" "USO" ...
  Indexed by objects of class: [POSIXt,POSIXct] TZ: GMT
  xts Attributes: 
 NULL

I now save:
 > save(vdf,file="vdf.Rdata")

I then open up vdf.Rdata, very different and i lose data.

str(vdf)
 xts [1:2919, 1:9] 87.3 87.2 87.2 87.2 87.2 ...
 - attr(*, "dimnames")=List of 2

 - attr(*, ".indexTZ")= Named chr "GMT"
  ..- attr(*, "names")= chr "TZ"
 - attr(*, ".indexCLASS")= chr [1:2] "POSIXt" "POSIXct"
