| as.data.frame.SpliceExprSet {splicegear} | R Documentation |
Convert a SpliceExprSet object to a data.frame
as.data.frame.SpliceSites(x, row.names = NA, optional = NA) as.data.frame.SpliceExprSet(x, row.names = NA, optional = NA)
x |
object SpliceSites-class or SpliceExprSet-class |
row.names |
NULL or a character vector giving the row names for the
data frame. Missing values are not allowed |
optional |
logical. If TRUE, setting row names is optional. |
Data are traditionally stored in objects of class data.frame.
This function links the object-oriented design of the package with
the large amount of functions working on data.frames.
A data.frame. For both functions the first column names are begin,
end, isintypeI, isintypeII, exprs and
genenames.
In the case of as.data.frame.SpliceExprSet, the next variable names will the ones in the
phenoData-class attribute of the
exprSet-class object belonging the
SpliceExprSet-class. The last variable names will be the
ones in the slot info of the Probes-class object.
