## Univariate projection or marginalization of a Dirichlet mixture density on on `[0,1]`

### Description

Plots a univariate Dirichlet mixture (in other words, a Beta mixture) angular density for extreme bi-variate data.

### Usage

```ddirimix.grid1D(
par = get("dm.expar.D2k4"),
wei = par\$wei,
Mu = par\$Mu,
lnu = par\$lnu,
npoints = 30,
eps = 10^(-3),
coord = c(1, 2),
marginal = TRUE,
invisible = TRUE,
displ = TRUE,
add = FALSE,
...
)
```

### Arguments

 `par` The parameter list for the Dirichlet mixture model. `wei` Optional. If present, overrides the value of `par\$wei`. `Mu` Optional. If present, overrides the value of `par\$Mu`. `lnu` Optional. If present, overrides the value of `par\$lnu`. `npoints` number of points on the 1D discretization grid. `eps` the minimum value ( = 1- the maximum value) of the grid points. `coord` A vector of size 2: the indices of the coordinates upon which the marginalization or projection is to be done if the dimension of the sample space is greater than two. `marginal` logical. If `TRUE`, the angular density corresponds to the marginal intensity measure of the extreme Poisson process, over coordinates `coord`. Otherwise, it is only the projection of the full dimensional angular measure (hence the moments constraints is not satisfied anymore). `invisible` Logical: should the result be returned as invisible ? `displ` Logical: should a plot be issued ? `add` Logical: should the density be added to the currently active plot ? `...` Additional arguments to be passed to `plot`

### Value

The discretized density on `[eps, 1-eps]` (included in [0,1])
