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.
