Gen.matrix(XX / ((2 - (XX = XX)) * sqrt(XX * XX)),ĥ) cov2cor Except for the weights R actually has a function that does exactly this. In R, a matrix is a collection of elements of the same data type (numeric, character, or logical) arranged into a fixed number of rows and columns. In R, we have a dedicated function t() to do. ![]() ![]() When you do so, columns of your matrix will become the rows and rows will become the new columns. It is a data structure in the R programming language. ![]() ![]() Taking the transpose of a matrix is nothing but switching/flipping between the rows and the columns. What is Matrix in R A matrix is an R object with a two-dimensional rectangular layout in which all the elements are arranged. 1) outer - 1 Use outer as shown: d <- diag(X)įunction(i) X / ((2 - (X = X)) * sqrt(X * X))))ģ) outer - 2 or a different way to use outer: f <- function(i, j) X / ((2 - (X = X)) * sqrt(X * X))Ĥ) list comprehension There are several CRAN packages that implement list comprehensions including comprehenr, eList and listcompr. Taking the transpose of a matrix is one of the common tasks in matrix algebra.
