prop <- new_pkg_download_proposal("ggplot2", config = list(cache_dir = target_dir))
prop$resolve()
prop$download()
prop$get_downloads()
dir(target_dir)
Installation
How to install a package into a new library?
library(pkgdepends)
dir.create(new_lib <- tempfile())

prop$solve()
prop$download()
prop$install()
lib_status(new_lib)
How to update a package?
Install an older version first.
library(pkgdepends)
dir.create(new_lib <- tempfile())
config <- list(library = new_lib)
prop <- new_pkg_installation_proposal("cran/pkgconfig@2.0.2", config = config)
prop$solve()
prop$download()
prop$install()
lib_status(new_lib)
Now update.
library(pkgdepends)
prop2 <- new_pkg_installation_proposal("pkgconfig", config = config)
prop2$set_solve_policy("upgrade")
prop2$solve()
prop2$download()
prop2$install()
lib_status(new_lib)
