I am trying to install a package that is not available at CRAN any more: frontiles
I have downloaded de package (frontiles_1.2.tar.gz) and tried to uploaded it manually using RStudio, and I get the following error:
ERROR: dependencies 'classInt', 'rgl', 'sp' are not available for package 'frontiles'
Is there any way for installing these dependencies so I can then install the package frontiles?
I am really not an expert in coding and informatics, so I would appreciate very clear step by step answers, so I am able to follow your advice...
Thank you in advance!!
