getDatasetList

R Documentation

Get list of all available dataset identifiers

Description

Get list of all available dataset identifiers that satisfy all specified constraints (see Arguments).

Usage

getDatasetList(...);

Arguments

...

Optional arguments can be passed to the function for more specific requests:

platform: The platform of the chip on which a measurement was done. A platform is identified by its GEO accession code. If specified, only datasets on the given platform are returned.
norm: Type of normalization to use when pre-processing a dataset. Possible values: "ORIGINAL", "FRMA"[1], "SCAN"[2]. If specified, only datasets for which the given preprocessed data is available are returned.
query: If specified, only datasets for which the query keyword appears in either the title or description of the dataset. typical example queries are 'Thyroid Cancer', 'Primary vs Metastasis', 'p53', etc.
curated: If curated = TRUE is specified, only manually curated datasets will be returned.

Value

A list of dataset identifiers.
