Is there a R function which would return a predefined min & max value if the computed value exceeds the range?

Question

I have a formula. When r calculates the value, if the result is between 0 and 1, the function should return the computed value. But, if it is below 0, the function should return 0, and if it is above 1, the function should return 1.

Is there an efficient way to do it without using the if function?

I found a javascript code that does what I want to do in R. Here it is:

clip = (a, b, t) => Math.min(Math.max(t, a), b)

please translate `x <- y - z` in english – Mister Jojo Nov 05 '22 at 18:25 — Mister Jojo, Nov 05 '22 at 18:25
`pmin(pmax(t, a), b)` does the work for t vectors.. – Ric Nov 05 '22 at 18:29 — Ric, Nov 05 '22 at 18:29

In Javascript, you could guard with Math.min and Math.max with lower and upper bound.

const
    x = (y, z) => Math.max(Math.min(y - z, 1), 0);

console.log(x(1, 2));   // 0
console.log(x(2, 0));   // 1
console.log(x(1, 0.5)); // 0.5

User ask about "R" language not js – Ric Nov 05 '22 at 18:31

right. question is tagged with [javascript] and i assume this approach should work with R as well. – Nina Scholz Nov 05 '22 at 18:34
