WebFeb 2, 2024 · cluster analysis hierarchical clustering r One Answer The issue here is that you have specified K.max as 100, however, you only have eight observations in your dataset. As noted in the clusGap documentation, K.max is the the maximum number of clusters to consider, hence, in your case, K.max cannot be greater than seven. WebMay 25, 2024 · clusGap() calculates a goodness of clustering measure, the “gap” statistic.

Gap Statistic for Estimating the Number of Clusters — clusGap
WebNov 8, 2024 · clusgap (Required). An object of S3 class "clusGap", basically a list with components. See the clusGap documentation for more details. In most cases this will be the output of gapstat_ord, or clusGap if you called it directly. title (Optional). Character string. The main title for the graphic. Default is "Gap Statistic results". WebI'm using the GAP statistics (clusGAP) to find the optimal number of clusters in my gene expression data. But I'm not sure whether the optimal number suggested by clusGAP is right or not. I ran the clusGAP for several times (clustGAP (data, kmeans, K.max = 30, B = 100)) , but I received different results as follow: WebApr 20, 2024 · gap_stat <- clusGap(nor, FUN = kmeans, nstart = 25, K.max = 10, B = 50) fviz_gap_stat(gap_stat) In this method also optimal number of cluster is 5. Conclusion. K-means clustering is a very simple and fast algorithm and it can efficiently deal with very large data sets. K-means clustering needs to provide a number of clusters as an input ... cushion for small of back
