eSet
object from a GSE data source.
GSE2eSet(gse, colBy, colID)
ExpressionSet
object.
ExpressionSet
(abbreviated
eSet
) object using the GDS2eSet
function available from the GEOquery package.
However, not all GSE data files have a corresponding GDS data file available. To convert GSE
data files into eSet
objects, exprso
provides this convenience function.However, the user should note that GSE data files do not always get stored in an easy to parse format. Although this function has worked succesfully with some GSE data files, we cannot make any guarantee that it will work for all GSE data files.
To acquire GSE data files, use the function getGEO
from the GEOquery package (e.g.,
getGEO("GSExxxxx", GSEMatrix = FALSE)
). For more information, see the GEOquery package.
