Dear Finance People:

I used the "get.hist.quote" to get the S&P as seen below:

>  spc <- get.hist.quote(instrument = "^gspc", start = "1998-01-01",
+               quote = "Close")
trying URL 'http://chart.yahoo.com/table.csv?s=^gspc&a=0&b=01&c=1998&d=3&e=05&f=2010&g=d&q=q&y=0&z=^gspc&x=.csv'
Content type 'text/csv' length unknown

time series starts 1998-01-02


Then I use the to.weekly to convert to weekly data:

> spc.w <- to.weekly(spc)
> str(spc.w)
An ‘xts’ object from 1998-01-02 to 2010-04-05 containing:
  Data: num [1:641, 1:4] 975 977 939 979 957 ...
 - attr(*, "dimnames")=List of 2
  ..$ : NULL
  ..$ : chr [1:4] "spc.Open" "spc.High" "spc.Low" "spc.Close"
  Indexed by objects of class: [Date] TZ: 
  Original class: 'zoo'  
  xts Attributes:  
 NULL
> 

My question is:  I  only need the "Close" section.  The other ones (Open, High, Low) are duplicates.  Is there a way just to return the Close component, please?

thanks,
Erin
