normScaleMarray {maigesPack} | R Documentation |
This function loads a maigesRaw
or maiges
object and scale adjust (normalise between arrays) the data using
functions from marray package.
normScaleMarray(obj=NULL, ...)
obj |
object of type maigesRaw or
maiges to be normalised. |
... |
additional parameters for function
maNormScale . |
This function for scale adjustment is entirely based on function
maNormScale
from marray package. See the
help page for this function to see how to set the parameter. Pay
attention to the subset
argument that is fixed directly from
the UseSpots
and BadSpots
from obj
object, and
must not be specified in the additional arguments.
The functionality of the scale adjustment function from marray
package was added because it uses an estimator of MAD different from
that one used in limma package. Also, using
maNormScale
function it is possible to do print
tip scale adjustment.
This function returns a maiges
object.

## Loading the dataset data(gastro) ## Doing global MAD scale adjustment gastro.norm = normScaleMarray(gastro.norm, norm="globalMAD") boxplot(gastro.norm) ## To see the effect of MAD adjustment ## For print tip MAD use the following command ## Not run: gastro.norm = normScaleMarray(gastro.norm, norm="printTipMAD") ## End(Not run)
