Construct a GEO landing page and open it directly in the system's default web browser (or a user-specified browser).
Usage
geo_show(
accession,
famount = NULL,
scope = NULL,
over_https = NULL,
browser = getOption("browser")
)
Arguments
- accession
A character of GEO accession IDs. Examples:
DataSets (GDS):
"GDS505"
,"GDS606"
,"GDS1234"
,"GDS9999"
, etc.Series (GSE):
"GSE2"
,"GSE22"
,"GSE100"
,"GSE2000"
, etc.Platforms (GPL):
"GPL96"
,"GPL570"
,"GPL10558"
, etc.Samples (GSM):
"GSM12345"
,"GSM67890"
,"GSM112233"
, etc.
- famount
A character specifying file/amount type requested. GEO data can be accessed through two sites:
Direct FTP/HTTPS file retrieval from GEO FTP server (file type):
"soft"
: SOFT (Simple Omnibus in Text Format) from GEO FTP site. Whenaccession
isDataSets
orSeries
, this is the default."soft_full"
: full SOFT (Simple Omnibus in Text Format) files from GEO FTP site by DataSet (GDS) containging additionally contains up-to-date gene annotation for the DataSet Platform."miniml"
: MINiML (MIAME Notation in Markup Language, pronounced miniml) is an XML format that incorporates experimental data and metadata. MINiML is essentially an XML rendering of SOFT format."matrix"
: Series matrix file."annot"
: annotation files for Platforms."suppl"
: supplementary files.
The following table summarizes the compatibility between GEO accession types and file type options:
famount GDS GSE GPL GSM SOFT (soft) o o o x SOFTFULL (soft_full) o x x x MINiML (miniml) x o o x Matrix (matrix) x o x x Annotation (annot) x x o x Supplementaryfiles (suppl) x o o o Accession-based queries to the NCBI GEO database (amount of data):
"none"
: Applicable only to DataSets; for DataSets, this is also the sole valid option."brief"
: accession attributes only."quick"
: accession attributes + first 20 rows of the data table."data"
: omits the accession's attributes, showing only links to other accessions and the full data table."full"
: accession attributes + complete data table.
- scope
A character specifying which GEO accessions to include (Only applicable to NCBI GEO database access).
"none"
: Applicable only to DataSets; for DataSets, this is also the sole valid option"self"
: the queried accession only."gsm"
,"gpl"
,"gse"
: related samples, platforms, or series."all"
: all accessions related to the query (family view).
- over_https
Logical scalar. If
TRUE
, connects to GEO FTP server via HTTPS (https://ftp.ncbi.nlm.nih.gov/geo); otherwise uses plain FTP (ftp://ftp.ncbi.nlm.nih.gov/geo). Only applicable to GEO FTP server access.- browser
a non-empty character string giving the name of the program to be used as the HTML browser. It should be in the PATH, or a full path specified. Alternatively, an R function to be called to invoke the browser.
Under Windows
NULL
is also allowed (and is the default), and implies that the file association mechanism will be used.
