## Histograms of non-rejection rates

### Description

Plots the distribution of non-rejection rates.

### Usage

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

### Arguments

`nrrMatrix` | matrix of non-rejection rates.
`K` | concentration matrix of the generative distribution (whenever available).
`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

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

    I <- qpRndGraph(n.vtx=nVar, n.bd=maxCon)
    K <- qpI2K(I)

    X <- qpSampleMvnorm(K, nObs)

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

    qpHist(nrr.estimates, K)
