netbenchmark.data: Benchmarking of several network inference algorithms for your own data

Description

Benchmarking of several network inference algorithms for your own data

Usage

netbenchmark.data(methods = "all.fast", data = NULL, true.net = NULL,
  eval = "AUPR", no.topedges = 20, sym = TRUE, plot = FALSE,
  verbose = TRUE)

Arguments

methods

A vector of characters containing the names of network i inference algorithms wrappers to be compared (default: "all.fast").

data

data.frame containing the data. Each row should contain a microarray experiment and each column a gene (default: NULL).

true.net

matrix containg underlying network in the form of adjacency matrix (default: NULL).

eval

The name of the evaluation metric among the following ones: "no.truepos", "AUROC" or "AUPR" (default : "AUPR").

no.topedges

Float specifying the percentage number of links to be considered in the evaluation (default: 20)

sym

Logical specifying if the evaluation is symmetric (default: TRUE) - see evaluate

plot

(default: FALSE)

verbose

Logical specifying if the code should provide a log about what the function is doing (default: TRUE).

Value

• netbenchmark.data returns a list with three elements.
  1. A data.frame which is the result table of the selected measure.
  2. A data.frame which contains the CPU Time Used (in seconds) by the algorithm to infer the network.
  3. A list containing the mean precision recall curves of the different algorithms for each datasource.
  Each of these data.frame will have the same number of columns as methods provided by the user and an additional one for a random method.

Details

The argument methods accepts "all.fast" and "all" (case insensitive) as a parameters:

• "all.fast" performs network inference with "aracne", "c3net", "clr", "GeneNet", "mutual ranking", "mrnet", "pcit" (and registered methods withRegisterWrapper.)
• "all" performs network inference with "aracne", "c3net", "clr", "GeneNet", "Genie3", "mutual ranking", "mrnet", "mrnetb", "pcit" (and registered methods withRegisterWrapper.)

All the measures only evaluates the first no.topedges % of the possible links inferred by each algorithm at each dataset.
