I am trying to implement the package "greenbrown" in R in order to conduct some studies on plant phenology. This package requires a number of dependencies, including "phenopix," which R fails to install. The error reported in the console is as follows: "ERROR: dependencies 'SDMTools', 'bcp' are not available for package 'phenopix'
* removing 'D:/R-SOFTWARE/R-4.0.5/library/phenopix'
Warning in install.packages :
installation of package 'phenopix' had non-zero exit status"
Searching in interner I found that the package 'phenopix' was removed from the CRAN repository.
Can anyone tell me how I can solve this problem? Is there any way to retrieve the package even though it was removed? Or are there alternative packages that I can use equally?
