Hi,
I'm still fairly new to all this so this may be a simple question. I
have a
problem sometimes when using the plotDensities function in Limma, in
some
cases the plot produced is on such a scale that the lines are not
distinguishable. Usually the intensity axis is in the range of -10
:30,
however ocassionally after a printtip lowes normalisation, or some
betweenArrayNormalizations, the scale of the graph is -5000:10000 with
the
density peak being a single spike in the middle of the plot. Is there
a way
to control the axis scale? or is there an easy way to set a minimum
and
maximums for an MA object?
Many thanks
Pete
