R help - Jun 2011 - access objects by name

Hi,

I have several data structures (xts structures).  I then have a list of the
names of those objects.

I'd like to access the object by name.

For example:

foo1 <- as.xts(....)
foo2 <- as.xts(...)
foo3 <- as.xts(...)

structs <- c("foo1", "foo2", "foo3")

for (thisOne in structs){
	print(thisOne$colA)
}

The above fails.  Clearly I'm missing a step translating the name to the
object.

Suggestions?

Thanks

for (thisOne in structs){
    print(get(thisOne)$colA)
}

you need to 'get' (retrieve) the object first.
