I am following instructions online for cluster analysis using the mclust package, and keep getting errors. http://www.statmethods.net/advstats/cluster.html These are the instructions (there is no sample dataset unfortunately): # Model Based Clustering library(mclust) fit <- Mclust(mydata) plot(fit, mydata) # plot results print(fit) # display the best model This is what I did and the error I get:> library(mclust) > fit <- Mclust(mydat) > plot(fit, mydat) #plot resultsError in match.arg(what, c("BIC", "classification", "uncertainty", "density"), : 'arg' must be NULL or a character vector My data is arranged so I have each row representing one individual with 9 values for morphological data. I want to see if they will group into 2 clusters, representing gender. I have tried using the instructions from the cran-r website, but they didn't work either Any help would be great, thank you -- View this message in context: http://r.789695.n4.nabble.com/cluster-analysis-error-mclust-package-tp4650842.html Sent from the R help mailing list archive at Nabble.com.
