Usage
smacofRect(delta, ndim = 2, circle = c("none","row","column"), weightmat = NULL, init = NULL, verbose = FALSE, itmax = 1000, reg = 1e-6, eps = 1e-6)
unfolding(delta, ndim = 2, circle = c("none","row","column"), weightmat = NULL, init = NULL, verbose = FALSE, itmax = 1000, reg = 1e-6, eps = 1e-6)
Arguments
delta
Data frame or matrix of preferences, ratings, dissimilarities.
circle
If "column"
, the column configurations are restricted to be on a circle, if "row"
, row configurations are on a circle, if "none"
, there are no restrictions on row and column configurations
weightmat
Optional matrix with dissimilarity weights
init
Matrix with starting values for configurations (optional)
verbose
If TRUE
, intermediate stress is printed out
itmax
Maximum number of iterations
reg
Regularization factor, prevents distances from being 0
