compareMedianTaxonGroups: Compare the median values of a variable between 2 taxon...

In PhyloProfile: PhyloProfile

Description

Given the phylogenetic profiles that contains up to 2 additional variables besides the presence/absence information of the orthologous proteins. This function will compare the median scores of those variables between 2 different taxon groups (e.g. parasitic species vs non-parasitic species), which are defined as in-group and out-group. In-group is identified by the user. Out-group contains all taxa in the input phylogenetic profiles that are not part of the in-group.

Usage

compareMedianTaxonGroups(data, inGroup, useCommonAncestor, variable)

Arguments

data	input phylogenetic profile in long format (see ?mainLongRaw and ?createLongMatrix)
inGroup	ID list of in-group taxa (e.g. "ncbi1234")
useCommonAncestor	TRUE/FALSE if using all taxa that share the same common ancestor with the pre-selected in-group as the in-group taxa. Default = TRUE.
variable	name of the variable that need to be compared

Value

List of genes that have a difference in the variable's median scores between the in-group and out-group taxa and their corresponding delta-median.
