text: user2005: I just followed the tutorial trying to do clustering on my own data, but I can't visualize it because fviz_cluster function is giving me an error:
  
  Error in if (xlab == "x") xlab <- "x value" : argument is of length zero
  
  Here is the code I am running:
  library("fpc")
  db <- fpc::dbscan(rtsne$Y, eps = 0.15, MinPts = 5)
  # Plot DBSCAN results
  library("factoextra")
  fviz_cluster(db, data = rtsne$Y, stand = FALSE,
          ellipse = FALSE, show.clust.cent = FALSE,
           geom = "point",palette = "jco", ggtheme = theme_classic())
  
  How can I make fviz_cluster function working?
  
  Update
  
  Filed a bug: https://github.com/kassambara/factoextra/issues/62
  
  user2005: I actually found an answer just accidentally. It is very unfortunate that factoextra documentation does not explicitly say that data parameter should be of data.frame type. In my case rtsne$Y was a matrix. The error that factoextra is giving is very uninformative.
  Here is the code that ultimately worked:
  fviz_cluster(db, 
  ----->  data = as.data.frame(rtsne$Y), 
          stand = FALSE,
          ellipse = FALSE, show.clust.cent = FALSE,
          geom = "point",palette = "jco", ggtheme = theme_classic())
