isa_ID_find: Find IDs of nodes or properties

In isaeditor: Tools to Manipulate ISA-Tab Files

Description

Find IDs of nodes or properties fullfilling specified criteria

Usage

isa_ID_find(x, node_pattern = NULL, value_pattern = NULL, prop_pattern = NULL)

Arguments

x	object of class isatab
node_pattern	return only nodes which match the given pattern
value_pattern	return only nodes which match one of the values
prop_pattern	return only nodes which match one of the properties

Details

Note: IDs are a thing internal to this R package. They are not imported from or exported to actual ISA-tab files. However, given that the node 'identifiers' (e.g. 'Sample Name') can be ambiguous, IDs are necessary to unambiguously identify a node.

Value

Character vector of IDs
