[R] removing values from a vector, where both the value and its name are the same?

[Patrick Burns]

In case it matters, the given solution has a problem if the
data look like:

x <- c(sum=77, test=99, sum=99)

By the description all three elements should be kept, but
the duplicated solution throws out the last element.  A more
complicated solution is:

unique(data.frame(x, names(x)))

(and then put the vector back together again).
