qpHist {qpgraph} | R Documentation

## Histograms of non-rejection rates

### Description

Plots the distribution of non-rejection rates.

### Usage

    qpHist(nrrMatrix, A=NULL,
           titlehist = "all estimated\nnon-rejection rates", freq=TRUE)

### Arguments

`nrrMatrix` | matrix of non-rejection rates.
`A` | adjacency matrix of an undirected graph whose present and missing edges will be employed to show separately the distribution of non-rejection rates.
`titlehist` | main title of the histogram(s).
`freq` | logical; if TRUE, the histograms show frequencies (counts) of occurrence of the different non-rejection rate values; if FALSE, then probability densities are plotted

### Details

This function plots histograms using the R-function `hist` and therefore the way they are displayed follows that of this R-function.

### Value

None

### Examples

    require(mvtnorm)

    nVar <- 50  ## number of variables
    maxCon <- 5 ## maximum connectivity per variable
    nObs <- 30  ## number of observations to simulate

    A <- qpRndGraph(p=nVar, d=maxCon)
    Sigma <- qpG2Sigma(A, rho=0.5)
    X <- rmvnorm(nObs, sigma=as.matrix(Sigma))

    nrr.estimates <- qpNrr(X, q=5, verbose=FALSE)

    qpHist(nrr.estimates, A)
