COMPCLUS is a program for rapid initial clustering of large data sets. It is executed interactively (see Vegetatio 42:103-111).

For each cluster a composite sample is produced which is simply the average of the samples contained; these composite samples are often useful for subsequent analysis by ordination or by hierarchical clustering.

Computing requirements are linear with respect to the amount of data, and thousands of species and samples are practical. The computing time for clustering is on the order of the time required merely to read the data.

The MS-DOS^TM executable module is dimensioned for 3,000 Species, 5,000 Samples, 27,000 non-zero array elements.
