However, if we agree that "$" is (as it should be) syntactic sugar for get(), then why do we have different behaviour for what should essentially be the same operations, albeit the former being easier to read and write than the latter? Or is my premise mistaken and that is the whole point of having "$" and get() which are not identical? > But then it would be inconsistent with what it does in other situations. I am afraid that I did not fully understand this point. What would the inconsistencies be in other situations? -Trishank ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
