Multidimensional scaling (MDS) in 2 dimensions
MDSmap(data, std = TRUE)
data |
a numeric matrix, data frame or |
std |
logical; if TRUE, |
If data
is an object of class "dist"
, std
is not active and data
is directly inputted into MASS::isoMDS
.
An object of class MDSmap
, i.e. a list with 4 objects:
points
, a 2-column vector of the fitted configuration (see isoMDS
);
stress
, the final stress achieved in percent (see isoMDS
);
data
, the input data frame;
std
, the logical std
input.
