When I run my kmeans algorithm I get this error
Error in kmeans(dat[, -1], k) : 
more cluster centers than distinct data points.
How can this error be fixed? I am 99% sure my data points are distinct. Here is my code
withinVar <- c() 
for (k in 2:30) { 
  km <- kmeans(dat[, -1], k) 
  withinVar <- c(withinVar, km$tot.withinss) 
}
