Subject: Problem with clusplot
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?
Thanks
