I'm trying to determine the number of cluters (elbow method and silhouette and gap statistic method) with function fviz_nbclust
knowing that at this point I'm only reproducing an example I found on Rpubs.com thanks in advance for your help
I tried for all three methods , this
fviz_nbclust(df, kmeans, method = "wss") + geom_vline(xintercept = 4, linetype = 2)+ labs(subtitle = "Elbow method")
and this
elbow_method <- fviz_nbclust(cust_data, FUNcluster = kmeans, method = "wss") elbow_method
I keep getting this error message: Error in call_with_cleanup(map_impl, environment(), .type, .progress, : object 'cleancall_call' not found
