intersection
:i
contains the number of common elements
of two lists up to position i
. The columns correspond to lists,
either obtained from altered datasets or by applying multiple
ranking procedures.overlapscore
:intersection
.noinformation
:"intersection"
and
"overlap score"
containing for each list position intersection counts and overlap scores
one would expect in the no-information case, corresponding to the random generation of
two mutually independent lists.scheme
decay
show(object)
for brief information.summary(object), measure = c("overlapscore", "intersection"), display = c("summary", "all"), position, digits = 3
for
condensed output. The argument measure
specifies the measure one is interested in. The argument display
controls whether only a five-point summary is printed (display = "summary"
) or whether all results
are printed (display = "all"
). The argument position
specifies the list position, e.g. if position = 10
, then
intersection counts/overlap scores up to position 10 are summarized. The argument digits
is used for number
formatting. Note that the output depends on scheme
.plot(object, frac=1/50, mode = c("mean", "all", "specific"), which = 1, ...)
produces a graphical display
of the intersection count (upper panel) and the overlap score (lower panel) for increasing list position, ranging from 1
to
frac*number of genes
. The argument mode specifies whether this is done as average over all
lists (mode = "mean"
), for a certain alternative list which
(mode = "specific"
) or
succesively in the form of separate plots for each alternative list (mode = "all"
). The ...
