Help HSDAR (Hyperspectral data analysis in R) package

Hi everyone, I would need a hand on the HSDAR (Hyperspectral data analysis in R) package with Rstudio.
I wanted to ask if there was anyone here available to help me out starting from 0.
Despite I follow the guide I have some difficulties since the first phases of operation (e.g. creating SpecLib).
I thank in advance who will be able to help me
