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
.
vector
s 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.
