![]() ncol which indicates the desired number of columns.nrows=3 indicates that the matrix should have three rows. The third argument nrow indicates the desired number of rows.By default, the matrix is filled by columns, byrow=FALSE. If we want the matrix to be filled column-wise, we set this argument to FALSE (That is, byrow=FALSE ). The argument byrow indicates that the matrix is filled row-wise.If we leave it blank, the matrix just won’t be filled. This is an optional argument and can be filled later. The first argument is the collection of elements that R will arrange into the rows and columns of the matrix.This constructs a matrix with 3 rows, containing the numbers 1 to 9, filled row-wise. Consider the following example: matrix(1:9, byrow=TRUE, nrow = 3) The matrix() function in R creates a matrix. A two-dimensional matrix is one that works only with rows and columns. ![]() 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.
