Paul,
Perhaps slightly better and more concise is
y <- -x + 1
Why multiply? Of course it may be optimized in some cases.

Wow! Amazing stuff.
It will take me a while to digest all that you have offered here.
I came up with a simple solution myself:
y<- (-1*x)+1

Thank you.
I came up with a slightly more complicated solution than yours myself:
y<- (-1*x) +1
I did not realize that adding a scalar to a vector would add that scalar to
each element of the vector. Nice!

The obvious answer is 1-x.
Another answer, which is good for converting any 0..n elements to any others,
is c(1,0)[x+1].
But the most important questions are
- where did x come from?
- what does it mean?
- why do you want to do this?
- what do you already know about R? Do you understand vector
Surely doing
y <- 1 - x
would be the simplest way?
Best,
Tom
