[R] inplace assignment

[David Hugh-Jones]

I get tired of writing, e.g.


data.frame[some.condition & another.condition, big.list.of.columns] <-
paste(data.frame[some.condition & another.condition,
big.list.of.columns], "foobar")


I would a function like:

inplace(paste(data.frame[some.condition & another.condition,
big.list.of.columns], "foobar"))

which would take the first argument of the inner function and assign
the function's result to it.

Has anyone done something like this? Are there simple alternative
solutions that I'm missing?

Cheers
David
