What you want is some sort of indexing nested lists based on names (as we
are used to for vectors, for example). As Ivan pointed out, I don't think
there's an out-of-the-box function in R that supports such indexing as it
requires some sort of mapping of the nested list's hierarchical structure.
stated there is C:\R\R-2.11.1\bin;.
