GroupProj {kimod} | R Documentation

## `GroupProj` of SelectVar object

### Description

This function calculates the relashionship between genes and samples from SelectVar method. Also, computes agglomerative hierarchical clustering of the dataset.

### Usage

    GroupProj(object, NGroups = 2, metric = c("euclidean", "manhattan"),
      method = c("ward", "single", "complete", "weighted", "flexible"), ...)

    ## S4 method for signature 'SelectVar'
    GroupProj(object, NGroups = 2, metric = c("euclidean",
      "manhattan"), method = c("ward", "single", "complete", "weighted",
      "flexible"), ...)

### Arguments

`object` | it is an object of SelectVar Class.
`NGroups` | An integer scalar or vector with the desired number of clusters.
`metric` | The character string specifying the metric to be used to calculate dissimilarities between observations. The currently available options are "euclidean" and "manhattan". Euclidean distances are root sum-of-squares of differences, and manhattan distances are the sum of absolute differences.
`method` | character string defining the clustering method. The methods implemented are "average" ([unweighted pair-] group [arithMetic] average method, aka b "single" (single linkage), "complete" (complete linkage), "ward" (Ward's method), "weighted" (weighted average linkage, aka b its generalization "flexible" which uses (a constant version of) the Lance-Williams formula and the par.method argument, and "gaverage" a generalized "average" aka b also using the Lance-Williams formula and par.method. (See `agnes`).
`...` | Additional parameters for `agnes`.

### Value

`GroupProj` | GroupProj with the corresponding completed slots

    Z1<-DiStatis(NCI60Selec)
    M1<-SelectVar(Z1,Crit="R2-Adj")
    A1<-GroupProj(M1,method="ward",metric="euclidean",NGroups=6)
    data(winesassesors)
    Z2<-DiStatis(winesassesors)
    M2<-SelectVar(Z2,Crit="R2-Adj")
    A2<-GroupProj(M2,method="ward",metric="euclidean",NGroups=6)
    }
