change values suitable to be passed to probes2table
, and
ultimately aafTableAnn
in the annaffy
package. This is an internal function and is not intended to be called
by end users.
makeFCList(x, indices, comps, dat)
x |
An indicator matrix showing up or down regulation based on
fold change, usually from a call to foldFilt . See details for
more information. |
indices |
A list created by a call to makeIndices . |
comps |
A list containing all the comparisons to be
made. Each list item should be a vector of length two. This should
be identical to the 'comps' argument used in the call to
foldFilt |
dat |
A matrix containing the expression values, usually
extracted using the exprs accessor. |
The purpose of this function is to create a list of named lists that
will be suitable to be passed to probes2table
, which will
result in a column of fold change values with a reasonable name when
output as an HTML or text table using annaffy.
