I have read the R documentation and some sources. As I understand it, the DBSCAN syntax in R automatically uses the Euclidean distance. For example like the following syntax:
kNNdist(data, k = 3)
kNNdistplot(data, k = 3)
abline(v = 21)
abline(h = 2.079)
dbscan(data, eps = 2.079, MinPts = 3)
What if I want to use Mahalanobis distance? Is it possible?
