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

Hi, is there an easy way to get the calculated weights in a regression equation? for e.g. if my model has 2 variables 1 and 2 with coefficient .05 and .6 how can I get the computed values for a test dataset for each coefficient? data var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients
