hi, When I try to use the function coordProj {mclust} " coordProj(diabetes[,-1],dimens=c(2,3),what="uncertainy",uncertainty=diabetesModel$uncertainty,parameters=diabetesModel$parameters) " to identify uncertainty, it errors and send this warning message: " Warning message: In coordProj(diabetes[, -1], dimens = c...

...t In addition: Warning messages: 1: best model occurs at the min or max # of components considered in: summary.mclustBIC(Bic, data, G = G, modelNames = modelNames) 2: optimal number of clusters occurs at min choice in: Mclust(as.data.frame(anc.st.mat)) 3: insufficient input for specified plot in: coordProj(data = data, parameters = x$parameters, z = x$z, what = "classification", That's puzzling because the example given by ?Mclust is something like plot(Mclust(iris[,-5]), iris[,-5]) which is pretty simple and dumbproof and works flawlessly... best, Federico -- Federico C.

...t. I use generated datasets, containing 5000 points in 20 dimensions with 5 clusters. The following poses a problem for me: emEst<-me(modelName="EEV",data=data[,1:numDimensions],z=unmap(x)) emEst<-me(modelName="VEV",data=data[,1:numDimensions],z=unmap(x)) coordProj(main="Model EEV",data,dimens=c(1,2),type="classification",ask=F,mu=emEst$mu,sigma=em Est$sigma,z=emEst$z) coordProj(main="Model EEV",data,dimens=c(1,2),type="classification",ask=F,mu=emEst$mu,sigma=em Est$sigma,z=emEst$z) For these two Models, ne...

...locations. They discovered something I didn?t expect; the data (called tur) is appended below. p <- qplot(x = dD, y = dCu65, data = tur, color = mine) print(p) # simple bivariate plot of the data; looks fine mod1 <- Mclust(tur[,2:3]) mod1$G mod2 <- Mclust(tur[,3:2]) mod2$G One can use coordProj to see the clusters found, but the basic result is that mclust found 3 clusters in mod1, but if you interchange the x and y columns it finds 7 clusters (mod2). Since this is bivariate data, I find this result pretty strange. The only thing I can think of is that it has something to do with how th...

Hi, A quick question from a social scientist new to R - how do I get coordProj / plot.Mclust to label the nodes by row names? Using "identify" only gives me the row numbers... Thanks. -- Bobby

Hi, quick question from a social scientist new to R: how do I add labels/row names to the nodes in coordProj / plot.Mclust plots? Apologies if this is a silly question...
