but I've been wrong before.
 Thanks.

Mark,

What's wrong with the following,

> head(sp.z)
              Open    High     Low   Close     Volume Adj..Close.
2000-01-03 1469.25 1478.00 1438.36 1455.22  931800000     1455.22

 colnames(sp.z)
[1] "Open"        "High"        "Low"         "Close"       "Volume"   
 
[6] "Adj..Close."

> colnames(sp.z)[1] = "OPEN"

> colnames(sp.z)
[1] "OPEN"    "High"        "Low"         "Close"       "Volume"     
[6] "Adj..Close."

HTH.

does anyone know how to put a column name on a zoo object. I think achim
and gabor are off line or they have gotten totally tired of me an
decided to ignore me ( which is totalyy understandable ).

logbidask<-log((aggfxdata[,"bid"] + aggfxdata[,"ask"])/2.0) logbidask
doesn't have a name and I can't figure out how to get one on it ?

aggfxdata is a zoo object.
