Class to Represent Scalar, Vector, or Matrix Structure

Source: R/flexstruc.R

The simplest way to create such objects is with the struc function.

# S4 method for struc,struc
*(e1, e2)

# S4 method for struc,struc
+(e1, e2)

# S4 method for struc,struc
%*%(x, y)

# S4 method for struc,struc
kronecker(X, Y)

# S4 method for struc
t(x)

# S4 method for struc
sum(x, ..., na.rm = FALSE)

# S4 method for struc
prod(x, ..., na.rm = FALSE)

# S4 method for struc
rowSums(x, na.rm = FALSE, dims = 1L)

# S4 method for struc
colSums(x, na.rm = FALSE, dims = 1L)

# S4 method for struc
dim(x)

Methods (by generic)

  • *: Elementwise or scalar multiplication

  • +: Elementwise or scalar addition

  • %*%: Matrix multiplication

  • kronecker: Kronecker product

  • t: Matrix or vector transpose

  • sum: Sum of vector or matrix elements

  • prod: Product of vector or matrix elements

  • rowSums: Row sums of matrices

  • colSums: Column sums of matrices

  • dim: Dimensions of a matrix

Slots

v

character vector giving the expressions for each element of the matrix structure object

dims

numeric vector giving the dimensions of the matrix structure object
