Hi All - I am using the daisy function from the cluster library to create a
dissimilarity matrix. I'm going to use that matrix to run a cluster
analysis. My participants are identified with the variable, hhid. However,
when I try to keep hhid in the dataset that I use to create the
dissimilarity matrix, daisy uses it to create the matrix rather than
ignoring it as an ID variable. I need to have the ID variable so I can
later on identify which cluster each participant was classified as. Any
thoughts would be much appreciated!
housing.cluster <-data.frame(hhid, htypec1, afforcr1, resyrc1, crowdcc1,
chprbos1)
housingdiss <- daisy(housing.cluster, metric="gower")
