Please provide an example of what you tried or a complete example (see 
posting guide in signature for tips). I get:

 > strsplit("O1 O2 O3", " ")
[1] "O1" "O2" "O3"

And if O1, O2, and O3 are objects then use ?get, as in:

O1 <- rnorm(10)
O2 <- rnorm(10)
O3 <- rnorm(10)
O <- strsplit("O1 O2 O3", " ")[[1]]
lapply(O, get)

Did you try help("<<-")?
