character, a vector that stores the Entrez Gene IDs tagged
in your dataset.
The order of the Entrez Gene IDs should match those of the count/expression
matrix row names.
species
character, determine the organism of selected gene sets:
"human", "mouse" or "rat".
min.size
integer, the minium number of genes required in a testing
gene set
updated
logical, set to TRUE if you want to download the most recent
KEGG pathways.
rdata.dir
character, directory from which the KEGG pathway
collections are loaded.
If NULL, EGSEA tries to load the data from EGSEAdata.
Details
It indexes the KEGG pathway gene sets and loads gene set annotation.
Value
indexed gene set annotation that can be used with other functions in
the package.
Each annotation is a list of seven elements: original stores the
original gene sets,
idx stores the indexed gene sets, anno that stores detailed
annotation for each
gene set, label a unique id that identifies the collection of gene
sets,
featureIDs stores the entrezIDs used in building the annotation,
species
stores that organism name of gene sets and name stores the
collection name
to be used in the EGSEA report.
Examples
library(EGSEAdata)
data(il13.data)
v = il13.data$voom
gs.annots = buildKEGGIdxEZID(entrezIDs=rownames(v$E), species="human")
