Clusters the data with one of the following methods:
Usage
immunr_hclust(.data, .k = 2, .k.max = nrow(.data) - 1, .method = "complete", .dist = TRUE)
immunr_kmeans(.data, .k = 2, .k.max = as.integer(sqrt(nrow(.data))) + 1,
.method = c("silhouette", "gap_stat"))
immunr_dbscan(.data, .eps, .dist = TRUE)Arguments
- .data
Matrix or data frame with features, distance matrix or output from repOverlapAnalysis or geneUsageAnalysis functions.
- .k
The number of clusters to create, defined as
kto hcut or ascentersto kmeans.- .k.max
Limits the maximum number of clusters. It is passed as
k.maxto factoextra::fviz_nbclust forimmunr_hclustandimmunr_kmeans.- .method
Passed to factoextra::hcut or as factoextra::fviz_nbclust.
In case of factoextra::hcut the agglomeration method is going to be used (argument
hc_method).In case of factoextra::fviz_nbclust it is the method to be used for estimating the optimal number of clusters (argument
method).- .dist
If TRUE then ".data" is expected to be a distance matrix. If FALSE then the euclidean distance is computed for the input objects.
- .eps
Local radius for expanding clusters, minimal distance between points to expand clusters. Passed as
epsto dbscan.
Value
immunr_hclust - list with two elements. The first element is an output from factoextra::hcut.
The second element is an output from factoextra::fviz_nbclust
immunr_kmeans - list with three elements. The first element is an output from kmeans.
The second element is an output from factoextra::fviz_nbclust.
The third element is the input dataset .data.
immunr_dbscan - list with two elements. The first element is an output from fpc::dbscan.
The second element is the input dataset .data.
