WebJul 16, 2024 · solve() and chol2inv() in Matrix package. Matrix is a package of classes and methods dealing with Matrix computations. These classes and methods are known as the S4.Different from the conventional data type in R, Matrix defines different classes for different matrices. For example, the standard dense numeric matrix is defined as … WebTrying to compute the inverse of a matrix manually is a hell of a job. However, not when it comes to R. R programming has a dedicated function to do the task for you. The solve() function in R programming takes a matrix as an argument and then returns the inverse of that matrix. Let us see an example for the solve() function in R programming:
