| getImage.AffymetrixCelFile {aroma.affymetrix} | R Documentation |
Creates an RGB Image object from a CEL file.
## S3 method for class '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)
other |
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. |
xrange, yrange |
vectors of length two specifying the
(x0,x1) and (y0,y1) regions to be extracted. If NULL, the
complete regions is used. |
field |
One of the CEL file fields, i.e. "intensities",
stdvs, or pixels. |
zoom |
A numeric scale factor in (0,+Inf) for resizing the
imaging. If 1, no resizing is done. |
palette |
An optional vector of color code. |
... |
Additional arguments passed to
*readRawDataRectangle() and more function. |
readRectFcn |
A function taking arguments 'xrange' and 'yrange',
or NULL for the default read function. |
verbose |
A logical or a Verbose object. |
Returns an Image object.
If palette==NULL, the color code is Grayscale, otherwise
TrueColor.
