probes2pathways: Extract pathways from "exemplars"
In mAPKL: A Hybrid Feature Selection method for gene expression data

Description Usage Arguments Details Author(s) Examples

The user may extract the pathways where the "exemplars" are involved with the aid of the reactome database.

1	probes2pathways(annotObj)

annotObj

The "Annot" class object.

This function utilizes the "Annot" class object as returned by the "annotate" function to extract the pathways where the "exemplars" are involved with the aid of the "reactome" database. We employ the probe Ids for the matching.

## We use the "exemplars" from the mAPKL.Rd example

exemplrs <- c(24, 26, 42, 45, 63, 81, 95, 99, 102, 113, 134, 135, 145, 152, 168)
names(exemplrs)<- c("215717_s_at", "1561358_at", "222752_s_at", "233922_at",
"218871_x_at", "33323_r_at", "244311_at", "220932_at", "205508_at", "209596_at",
"215180_at", "1560638_a_at", "201852_x_at", "229947_at", "221731_x_at")

gene.info <- annotate(exemplrs,"hgu133plus2.db")

## We now use the "gene.info" to identify the relevant pathways
