x |
object of class ExprTreeSet. |
transfo |
a valid function to transform the data, usually “log2”, or “0”. |
method |
method to compute M, “mean” or “median”. |
names |
optional vector of sample names. |
ylim |
range for the plotted M values. |
... |
optional arguments to be passed to plot. |
Produces mvaplots for slot data for an object of class ExprTreeSet.
For names=NULL full column names of slot data will be displayed while for
names="namepart" column names will be displayed without name extension. If names
is a vector of column names, only these columns will displayed as mvaplot.
