First, install the package devtools following the instructions depending on your operating system.
Then install git2r:
install.packages("git2r")
prosail uses Support Vector Regression (SVR) for hybrid inversion, currently based on the package liquidSVM.
Please follow installation instructions provided in the documentation webpage.
Once liquidSVM is installed, you may need to add the 32bit DLL into the R library. this i386 directory should be copied into the local 'Path_For_My_R_distribution\library\liquidSVM\libs' directory on your computer.
You need to install the package prospect with the following command line in R session:
devtools::install_gitlab('jbferet/prospect')
The package prosail can then be installed with the following command line in R session:
devtools::install_gitlab('jbferet/prosail')
A tutorial vignette is available here.
