Vignette reproducibility

[AlejandroP433]

The vignette/articles are not reproducible.

• In article/section 4, the package preprocS2 is required but is not explicitly on CRAN, R-universe, or explicitly describe how to install it.
• In section 5, chunck 1.1 gives imprecise instruction of directory creation. I think adding dir.create(data_dir, showWarnings = F, recursive = T) should be enough.
• The package biodivMapR is not on CRAN, R-universe, or explained how to install it.
• In section 3, the scatter plot are not 100% reproducible. I image is because pseudo-randomness in the estimation procedure. So adding a seed somewhere could help?

Thanks for your time :)

Thanks a lot for your suggestions. v3.1.0 follows these recommendations

• a section 'installation of preprocS2' is now added to section 4.
• dir.create(data_dir, showWarnings = F, recursive = T) has been added. The instruction 'The data should be placed in a directory defined as data_dir in the next code chunk.' was already given in the previous section, so this data_dir is assumed to be created manually or with an R command before downloading the data.
• the installation for the package biodivMapR is now more precisely identified with the following recommendations:

The full tutorial including spectral diversity mapping with the `biodivMapR` package is available [here](https://jbferet.github.io/biodivMapR/articles/biodivMapR_05.html).
Please visit the main [biodivMapR webpage](https://jbferet.github.io/biodivMapR) and follow instructions for installation.

• a seed has been added as optional input for train_prosail_inversion. The tutorial also explicitly defines a seed.
