How about this one? If I set a variable in a data.frame with a two- part name including a dot (say y.pair), and if the variable with the name of the first part (y) doesn't but I ask for it's value I get the value of the two-part name. Ie set fred$x.pair and print the value of fred$x it gives me the value I set to fred$x.pair. Weird and somewhat disturbing! Maybe an example makes it clearer:
