## gOverview

### Description

This function generates a graphic overview of the spectroscopic data.

### Usage

```
gOverview(data_abs, data_ndd, fontFamily = NULL)
```

### Arguments

`data_abs` |
A data frame, which contains in the first column the wave numbers and in the following columns the samples absorbances. |

`data_ndd` |
A data frame, which contains in the first column the wave numbers and in the following columns the samples second derivative values. |

`fontFamily` |
The desired graphic font family. |

### Value

- If
*data_ndd is provided*: It returns a grid with three plots:

The ensemble of all samples spectra.

The ensemble of the second derivative spectra of all samples.

The average and standard deviation spectra.

- If
*data_ndd is omitted*: It returns a grid with two plots:

The ensemble of all samples spectra.

The average and standard deviation spectra.
