[R] 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 
 # append cluster assignment
 mydata <- data.frame(mydata, fit$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?
