Rstudio error with the fviz_nbclust() function

4.8k views Asked by At

I'm doing a report for a data analysis and statistical learning subject.
The problem is in the clustering phase. I have to find the optimal number of clusters, and i already done. But when i try to display the graph with the following function it gives me an error:

nb<-NbClust(df, diss=NULL,distance="euclidean",method="average")

fviz_nbclust(nb)

Error in if (class(best_nc) == "numeric") print(best_nc) else if (class(best_nc) == :
the condition has length > 1

df is the standardized data set with only numerical data.
The error is referred to the fviz_nbclust function.
I'd like to know what to do. I have already try to reinstall the packages, RStudio, everything but nothing. I also did, inside the NbClust() function the min_nc or max_nc and stuff like that.

Thanks for your help.

I had the same problem and it turned out that the function fviz_nbclust (and also the hidden function .viz_NbClust as a matter of fact) is written wrongly. Specifically, the problem is the tests if (class(best_nc) == "numeric") and if (class(best_nc) == "matrix") in the both functions which are nonsense as the object best_nc, which is the element of the NbClust result nb$Best.nc, has actually two classes:

> class(nb$Best.nc)
[1] "matrix" "array"

So, the tests will fail as if can take only one logical value as the condition, but the tests produce two values:

> class(nb$Best.nc) == "numeric"
[1] FALSE FALSE
> if(class(nb$Best.nc) == "numeric") something()
Error in if (class(nb$Best.nc) == "numeric") something() : 
  the condition has length > 1

My solution: I had to fix the functions fviz_nbclust and .viz_NbClust so that the tests look like if (any(class(best_nc) == "numeric") ) and if (any(class(best_nc) == "matrix") ). Here is a working code:

library(factoextra)
library(NbClust)
# fix the functions
fviz_nbclust <- function (x, FUNcluster = NULL, method = c("silhouette", "wss", 
                                           "gap_stat"), diss = NULL, k.max = 10, nboot = 100, verbose = interactive(), 
          barfill = "steelblue", barcolor = "steelblue", linecolor = "steelblue", 
          print.summary = TRUE, ...) 
{
  set.seed(123)
  if (k.max < 2) 
    stop("k.max must bet > = 2")
  method = match.arg(method)
  if (!inherits(x, c("data.frame", "matrix")) & !("Best.nc" %in% 
                                                  names(x)))
