RESOURCERER.annotation.to.ID: Link RESOURCERER annotation file to expression ID
In SIM: Integrated Analysis on two human genomic datasets

Description Usage Arguments Details Value Author(s) See Also Examples

Get annotation out of the RESOURCERER annotation file and link them to expression data with help of expression ID's

1	RESOURCERER.annotation.to.ID(data, poslist, col.ID.link = 1, col.poslist.link = 1)

`data`	data.frame with expression data including an expression ID column.
`poslist`	data.frame containing the RESOURCERER annotation file
`col.ID.link`	numeric value, specifying the column of `data` that contains the ID to link with the `poslist`.
`col.poslist.link`	numeric value, specifying the column of `poslist` that contains the ID to link with the `data`.

This function will output the inserted dataset, including the necessary, for integrated.analysis, a nnotation columns: "CHROMOSOME", "STARTPOS"and "Symbol" out of the inserted RESOURCE RER annotation file poslist.

A data.frame is returned, containing a dataset with annotation columns which can be used for integrated.analysis
