stdAttrNames: MIRIAM annotation attributes

Description

These functions deals with conforming with MIRIAM annotation guidelines, conversion and mapping between MIRIAM identifiers.

Usage

stdAttrNames(graph, return.value = c("matches", "graph"))
fetchAttribute(graph, organism = "Homo sapiens", target.attr, source.attr, bridge.web = NPMdefaults("bridge.web"))

Arguments

graph

An annotated igraph object.

return.value

Specify whether to return the names of matched standard annotations, or modify the graph attribute names to match the standards.

organism

The latin name of the organism (Case-sensitive).

target.attr

The target annotation, given as MIRIAM standard in the format miriam.xxx

source.attr

The source annotation attribute from graph

bridge.web

The base URL for Brigde Database webservices.

Value

For stdAttrNames, matches gives the original attribute names and their MIRIAM version. Since this is done by simple text matching, mismatches may occur for ambiguous annotations (such as GO, EC number). graph returns the input graph with attribute names standardized.For fetchAttribute, the input graph with the fetched attribute mapped to vertices.

Examples

data(ex_kgml_sig)	# Ras and chemokine signaling pathways in human
 ## Modify attribute names to match MIRIAM standard annotations.
 graph <- stdAttrNames(ex_kgml_sig, "graph")
# Use Attribute fetcher to get affymetrix probeset IDs for network vertices.
 ## Not run: 
#    graph <- fetchAttribute(graph, organism="Homo sapiens",
#                    target.attr="miriam.affy.probeset")
#  ## End(Not run)
