Print method for ahp_matrix objects

Source: R/ahp.R
print.ahp_matrix.Rd

Displays a formatted summary of an AHP pairwise comparison matrix including the matrix itself, calculated weights, and consistency information.

Usage

# S3 method for class 'ahp_matrix'
print(x, ...)

Arguments

x

An object of class "ahp_matrix" created by create_ahp_matrix.

...

Additional arguments passed to print methods (currently unused).

Value

Invisibly returns the input object.

Details

The print method displays:

  • The pairwise comparison matrix with indicator names

  • Normalized weights for each indicator

  • Consistency Ratio (CR) with a status indicator

  • Maximum eigenvalue (lambda_max)

The consistency status shows a checkmark (✓) if CR <= 0.1 (acceptable consistency) or an X (✗) if CR > 0.1 (inconsistent judgments).

Examples

# Create an AHP matrix
pairwise <- matrix(c(
  1,   3,   5,
  1/3, 1,   2,
  1/5, 1/2, 1
), nrow = 3, byrow = TRUE)
ahp_result <- create_ahp_matrix(
  indicators = c("pH", "OM", "P"),
  mode = "matrix",
  pairwise = pairwise
)

# Print the result
print(ahp_result)
