deltaplot

R Documentation

An exploratory plot of discordance for delta selection.

Description

Returns a graph of non-overlap (discordance) of rankings represented by the sum of zeros across all objects in the δ-dependent Idata vector (see compute.stream) for a suitable range of δ values starting at δ=0. Graphs are plotted for all pairwise list combinations.

Usage

deltaplot(lists, deltas=NULL, subset.lists=NULL, subplot = FALSE,
perc.subplot=50, directory=NULL)

Arguments

`lists`	A data frame cotaining two or more columns that represent lists of ordered objects to be compared
`deltas`	The range of δ values to be examined, defaults to NULL. If not specified then `delta=c(1:nrow(lists)0.25)`. If `max(deltas)` is larger than `nrow(lists)`, then `deltas=deltas[which(deltas<nrow(lists)0.25)]`,
`subset.lists`	Specifies the subset of the input lists, which is used for calculating zero counts for the deltaplot. The value contained in `subset.lists` specifies which objects are taken for the calculation from each input list, e.g. a value of 100 would use the first 100 objects of each input list. Default is NULL, in which case all objects of each list are used. If specified and `max(deltas)` is larger than `subset.lists`, then `deltas=deltas[which(deltas<subset.lists*0.25)]`,
`subplot`	Logical: if TRUE an additional deltaplot is generated containing a detailed subplot positioned in the top right corner of the plot. This subplot encloses a configurable subset of the values of the original deltaplot. This subset can be specified via a percentage value using the `perc.subplot` parameter (default is FALSE for `subplot`).
`perc.subplot`	Percentage of the range of the main plot used for creating a subplot in the top right corner, default is 50(%). Subplot provides a detailed view of the main plot.
`directory`	Specifies the directory for saving the generated deltaplots in PDF format. In case `directory` is `NULL` (default), no pdf is created, but a new device will be opened.

Value

Mdelta

A list of δ-matrices for each comparison of ordered lists

Examples

set.seed(1234)
data(breast)
##plot subplot
a = deltaplot(breast, deltas = 1:50, subplot=TRUE)

##don't plot subplot (default)
a = deltaplot(breast, deltas=1:50, subplot = FALSE)
