I am using getSymbols function from quantmod package to get price data from
internet.

Currently I have:

my.ticker <- "IBM"
getSymbols(my.ticker,src="google")

This creates an xts object named my.ticker which contains historical price
data for IBM.

How can I call and manipulating this xts object using my original string
my.ticker?

I want to do:
colnames(my.ticker) <- c("open","high","low","close","vol")

If you want to change the colnames (an attribute) of the object now named "IBM" in your global environment, then look a:

?attributes
?attr


However, this does not work as my.ticker refers to the string "IBM" rather
than the xts object called IBM.

Out of desperation, I have also tried:
colnames(paste(my.ticker)) <- c("open","high","low","close","vol")
colnames(as.xts(my.ticker)) <- c("open","high","low","close","vol")

But why are you do this??? It already has a perfectly servicable set of names:

> colnames(get(my.ticker))
[1] "IBM.Open"   "IBM.High"   "IBM.Low"    "IBM.Close"  "IBM.Volume"
