Creates an RGB Image object from a CEL file.
# S3 method for AffymetrixCelFile
getImage(this, other=NULL, transforms=list(sqrt), xrange=c(0, Inf), yrange=xrange,
zrange=c(0, sqrt(2^16)), field=c("intensities", "stdvs", "pixels"), zoom=1, ...,
readRectFcn=NULL, verbose=FALSE)Returns an Image object as defined by the EBImage package.
If palette==NULL, the color code is Grayscale, otherwise
TrueColor.
An optional AffymetrixCelFile of the same chip type,
that is used for calculating the ratio (non-logged). Note, to get
the log-ratios, the log() function has to be specified as
the first transform in the list of transformations.
vectors of length two specifying the
(x0,x1) and (y0,y1) regions to be extracted. If NULL, the
complete regions is used.
One of the CEL file fields, i.e. "intensities",
stdvs, or pixels.
A numeric scale factor in (0,+Inf) for resizing the
imaging. If 1, no resizing is done.
Additional arguments passed to
*readRawDataRectangle() and more function.
A function taking arguments 'xrange' and 'yrange',
or NULL for the default read function.
A logical or a Verbose object.
