combine-methods: Combine two objects of class 'mgsa' into one.

In mogsa: Multiple omics data integrative clustering and gene set analysis

Description

This function could only be used to combine two "mgsa" objects at present; using "Reduce" function to combine more.

Usage

  combine(x, y, ...)

Arguments

x	one mgsa object
y	another mgsa object
...	ignored. Only two mgsa objects could be combined, using "Reduce" to combine more than two sets.

Value

A combined object of class mgsa will be returned.

Methods

signature(x = "mgsa", y = "mgsa")

To combine two objects of mgsa.

This function could only be used to combine two "mgsa" objects; using "Reduce" function to combine more.

Examples

  # library(mogsa)
  # loading gene expression data and supplementary data
  data(NCI60_4array_supdata)
  data(NCI60_4arrays)
  # split gene set annotation into two sets.
  sup1 <- lapply(NCI60_4array_supdata, function(x) x[, 1:10])
  sup2 <- lapply(NCI60_4array_supdata, function(x) x[, -(1:10)])
  # project two sets of annotation
  mgsa1 <- mogsa(x = NCI60_4arrays, sup=sup1, nf=9,
                proc.row = "center_ssq1", w.data = "inertia", statis = TRUE)
  mgsa2 <- mogsa(x = NCI60_4arrays, sup=sup2, nf=9,
                 proc.row = "center_ssq1", w.data = "inertia", statis = TRUE)
  # combine two indenpendent mgsa sets
  mgsa_comb <- combine(mgsa1, mgsa2)
  dim(getmgsa(mgsa1, "score"))
  dim(getmgsa(mgsa2, "score"))
  dim(getmgsa(mgsa_comb, "score"))
