simpleSampleSearch

The stupid man's GEOmetadb!

Installation:

source("http://bioconductor.org/biocLite.R")
biocLite("devtools")
biocLite("ttriche/simpleSampleSearch")

Usage:

library(simpleSampleSearch)
checkForUpdates() ## if there is a new release of the geoMetaDb database, pull it

Look for new Illumina HumanMethylation450 datasets:

getRecent(simpleSampleSearch:::HM450)
data frame with 10 rows and 2 columns
                                                          descr         gse

Get series with the word "glio" in their name, on Affy hgu133plus2, by most recent update:

getExperiments("glio", gpl="GPL570")
data frame with 10 rows and 2 columns
                                                          descr         gse

9       Genes regulated by miR-127-3p in glioblastoma cell line    GSE50173
10 DNA methylation alteration and gene expression sigature in b    GSE50774

Look at a particular series' details:

getDetails("GSE55541")
$title
[1] "Human ESC-based modeling of pediatric gliomas by K27M mutation in histone H3.3 variant"

$submission_date
[1] "2014-03-04"

$type
[1] "Expression profiling by array"

Coming soon(ish): SRA search that is less excruciating than NCBI's interface.
