Cube root of negative
WebOct 10, 2024 · There is no function in R to find the cube root of negative values, hence we need to create that. The code to create the function is as shown below −. CubeRoot<-function (x) { sign (x)*abs (x)^ (1/3) } Now we just need to pass the values in the function to find the cube root of those values. These values can be a vector or a single value as well. WebI'm trying to see if there is a function to directly get the real cube root of a negative number. For example, in Java, there is the Math.cbrt() function. I'm looking for the equivalent in R. Otherwise, my current hack is: x <- -8 sign(x) * abs(x)^(1/3) which is very inelegant and cumbersome to type every time. Thx!
