Dear all I'm trying to run a cluster analysis with R Here are the commands:
mydata <- na.omit(matrix) # listwise deletion of missing mydata <- scale(matrix) # standardize variables fit <- kmeans(mydata, 8) # 8 cluster solution # get cluster means aggregate(mydata,by=list(fit$cluster),FUN=mean) # append cluster assignment mydata <- data.frame(mydata, fit$cluster) library(cluster) clusplot(mydata, fit$cluster, color=TRUE, shade=TRUE, labels=2, lines=0) I get the following error Error in princomp.default(x, scores = TRUE, cor = ncol(x) != 2) : 'princomp' can only be used with more units than variables How can I fix it?
