Returns an estimate of the proportion of true null hypotheses using a convex decreasing density estimate on a vector of p-values.

1 |

`p` |
numeric vector of p-values, calculated using any test of your choice. Missing values are not allowed |

`niter` |
number of iterations to be used in fitting the convex, decreasing density for the p-values. Default is 100. |

`doplot` |
logical, should updated plots of fitted convex decreasing
p-value density be produced at each iteration?
Default is |

`doreport` |
logical, should the estimated proportion be printed at each iteration?
Default is |

The proportion of true null hypotheses is often denoted pi0.

Numeric value in the interval [0,1] representing he estimated proportion of true null hypotheses, with `class`

being `convest`

and the `lfdr`

attribute containing estimated local false discovery rates.
