'clusterEstimation' is a package that implements Fu and Perry's 2020 algorithm for estimating the number of clusters within a data set using Gabriel cross-validation. The premise of the function 'ClusterCV' is to determine the number of cluster with the smallest cross-validation error. This algorithm includes the option to use an un-adjusted or adjusted estimation of the number of clusters. The unadjusted method can be used to correct the overestimation of the number of clusters when correlation between dimensions is high. 'ClusterCV' function also provides the option to apply either k-means or spectral clustering methods within the estimation algorithm.
