The mapped set, in the output vectors of the samples of dset.
FUNCTION
The input vectors of dset are mapped using the existing
Sammon mapping in the global variables set and map
(see SAMMON-VARIABLES). Therefore, a check is made
to see if dset has the same dimensionality as set.
Each point is then triangulated
using the function sammon_triangulate. The mapped
point (2D) is then placed in the output vector of the
mapped SAMPLE; therefore, dset has to be an
IOSET (see DATASET-flags).
NOTE
This function can only be used for mappings to 2D. It calls
sammon_triangulate.
