Hi,
i want a cluster-analysis with clara, but getting an
error because in cldat are NA's.
Error in clara(cldat[, 1:3], 4) : Each of the random samples contains
objects between which
no distance can be computed.
cldatx <- subset(cldat,select=c(A,B,C))
cldaty <- na.omit(cldatx)
Now , clara works but cldat has ~193.000 obs
and cldatx without NA's ~75.000 obs.
How could i match back the clara result (cluster group)
to check associations with other attributes in the 193.000 obs
in the cldat.frame ?
Many thanks
Christian
