Have you tried using the 'db' argument to tools::package_dependencies?
rbind the common columns of installed.packages() and available.packages()
and use that as the package database.
installed <- installed.packages()
available <- available.packages()
commonCols <- intersect(colnames(installed),colnames(available))
db <- rbind(installed[commonCols,], available[commonCols,])
tools::package_dependencies("somePkg", db=db)
List the types of dependencies you want in the 'which' argument, e.g.
which=c("Depends","Imports","LinkingTo","Suggests").
In R-devel now (but not R-4.0.2 and I haven't downloaded 4.0.3 yet) you can
use nicknames for which ("strong"=DIL, "most"="strong"+"Suggests", or
"all"="most"+"Enhances") and can also use recursive=columnNames to use a
smaller set of columns when recursing. Recursing with "Suggests" or
"Enhances" can give you a huge number of usually irrelevant packages.
