getOrder {affycoretools} | R Documentation |
This function is used to create a list
containing the correct
order to output a set of probesets based on the fold change values for
those probesets. This is an internal function and is not intended to
be called by end users.
getOrder(fcList, order.by)
fcList |
A list of named lists, generally produced by a
call to makeFCList |
order.by |
One of 'sum', 'max', 'median', or 'mean'. This orders the output for those tables that have multiple fold change values based on the summary statistic chosen. Defaults to 'sum'. |
The purpose of this function is to come up with some ordering for
probesets that will be ouput by a call to vennSelectFC
. The
ordering for probesets unique to a given comparison is simple, since
there is only one fold change to be considered. However, when there
are more than one comparison, we have to decide how the probesets
should be ordered. The choices available include those that seemed
reasonable to me when I wrote this function. Presumably there are
other reasonable choices that may need to be included.
