Hi,
I want to create an alias for the "<-" function and then later
overwrite it. Any idea how I can get the "<-" function object? I know
for other functions it's easy, something like "f <- seq" will do; how
really no clue for this one. Thanks!
get("<-") will give it to you, and
`<-` <- function(x, y) cat("x=", x, "y=", y, "\n")
will change it -- and will probably be the last effective thing you do
in that session, unless you're really careful:

[1] 1

x= 1 y= 3
