I need help creating the equation for this function in R

The function should return a logical `TRUE` or `FALSE` (no quotes) depending on whether the sum of the last `n` elements of the vector `x` is equal to or larger than the sum of the other elements in `x`.No logical checks need to be built into the function that looks at the values of the arguments.

For example, if `x` is the vector`c(4,3,8,18)` and `n` is 1, then the function would return `TRUE` since 18 (sum of last 1 element) is equal to or larger than 15 (4+3+8; sum of other elements).If `x` is the vector`c(1,1,8,2,3)` and `n` is 2, then the function would return `FALSE` since 5 (2+3; sum of last 2 elements) is NOT equal to or larger than 10 (1+1+8); sum of other elements.
