inversionv

inversionv() returns the vector of inversions for each entry in the permutation. For example, inversionv(1,2,0) = (1,1,0), inversionv(0,1,2) = (0,0,0).

When using the R package  'exams'  to write mathematics questions in 'Sweave' files, the output of a lot of R functions need to be adjusted for display in mathematical formulas. Specifically, the functions were accumulated when writing questions for the  topics of the mathematics courses College Algebra, Precalculus, Calculus, Differential Equations, Introduction to Probability, and Linear Algebra.  The output of the developed functions can be used in 'Sweave' files.
