validate graph

Description

plotting the observed differential effects of an effect reporter and the expected differential effects of the regulating signalling gene

Usage

validateGraph(
  CNOlist,
  fc = NULL,
  expression = NULL,
  model,
  bString,
  Egenes = 25,
  Sgene = 1,
  parameters = list(cutOffs = c(0, 1, 0), scoring = c(0.1, 0.2, 0.9)),
  plot = TRUE,
  disc = 0,
  affyIds = TRUE,
  relFit = FALSE,
  xrot = 25,
  Rowv = FALSE,
  Colv = FALSE,
  dendrogram = "none",
  soft = TRUE,
  colSideColors = NULL,
  affychip = "hgu133plus2",
  method = "s",
  ranks = FALSE,
  breaks = NULL,
  col = "RdYlGn",
  sizeFac = 10^-10,
  order = "rank",
  verbose = TRUE,
  ...
)

Arguments

CNOlist	CNOlist object (see package CellNOptR), if available.
fc	m x l matrix of foldchanges of gene expression values or equivalent input (normalized pvalues, logodds, ...) for m E-genes and l contrasts. If left NULL, the gene expression data is used to calculate naive foldchanges.
expression	Optional normalized m x l matrix of gene expression data for m E-genes and l experiments.
model	Model object including the search space, if available. See CellNOptR::preprocessing.
bString	Binary string denoting the hyper-graph.
Egenes	Maximal number of visualized E-genes.
Sgene	Integer denoting the S-gene. See colnames(getSignals(CNOlist)[[1]]) to match integer with S-gene name.
parameters	parameters for discrete case (not recommended); has to be a list with entries cutOffs and scoring: cutOffs = c(a,b,c) with a (cutoff for real zeros), b (cutoff for real effects), c = -1 for normal scoring, c between 0 and 1 for keeping only relevant between -1 and 0 for keeping only a specific quantile of E-genes, and c > 1 for keeping the top c E-genes; scoring = c(a,b,c) with a (weight for real effects), c (weight for real zeros), b (multiplicator for effects/zeros between a and c);
plot	Plot the heatmap. If FALSE, only corresponding information is printed.
disc	Discretize the data.
affyIds	Experimental. Turn Affymetrix Ids into HGNC gene symbols.
relFit	if TRUE a relative fit for each E-gene is computed (not recommended)
xrot	See function epiNEM::HeatmapOP
Rowv	See function epiNEM::HeatmapOP
Colv	See function epiNEM::HeatmapOP
dendrogram	See function epiNEM::HeatmapOP
soft	if TRUE, assigns weights to the expected pattern
colSideColors	See function epiNEM::HeatmapOP
affychip	Define Affymetrix chip used to generate the data (optional and experimental).
method	Scoring method can be "cosine", a correlation, or a distance measure. See ?cor and ?dist for details.
ranks	if TRUE, turns data into ranks
breaks	See function epiNEM::HeatmapOP
col	See function epiNEM::HeatmapOP
sizeFac	Size factor penelizing the hyper-graph size.
order	Order by "rank", "name" or "none"
verbose	TRUE for verbose output
...	additional arguments for epiNEM::HeatmapOP

lattice object with matrix information
