That's rather dated: see the more recent reports on this list.

These are documented but still seem like serious deficiencies:
> f <- function(x, y) x + 10*y
> 3 |> x => f(x, x)
Error in f(x, x) : pipe placeholder may only appear once
> 3 |> x => f(1+x, 1)
Error in f(1 + x, 1) :
pipe placeholder must only appear as a top-level argument in the RHS call
Also
Gabor,
Although it might be nice if all imagined cases worked, there are many ways to
work around and get the results you want.
You may want to consider that it is easier to recognize the symbol you use (x
in the examples) if it is alone and used only exactly once and it the list of
function
If
3 |> x => f(x, y=x)
were allowed then I think that
runif(1) |> x => f(x, y=x)
be parsed as
f(runif(1), y=runif(1))
so runif(1) would be evaluated twice, leading to incorrect results from f().
