About: The apcluster package implements Frey's and Dueck's Affinity Propagation clustering in R. The package further provides leveraged affinity propagation, exemplar-based agglomerative clustering, and various tools for visual analysis of clustering results.

• plotting of clustering results extended to data sets with more than two dimensions (resulting in the clustering result being superimposed in a scatterplot matrix); the variant that plot() can be used to draw a heatmap has been removed. From now on, heatmap() must always be used.
• improved NA handling
• correction of input check in apcluster() and apclusterL() (previously, both functions issued a warning whenever argument p had length > 1)
• corresponding updates and further improvements of help pages and vignette
