I also found the file semantics over the network drive to be tricky to get right. In the drat documentation I refer to 'file://...' but I found accessing via http to be easier. But it still works. Quick example from work with one local repo (which I just copied to /tmp here): R> AP <- available.packages() R> dim(AP) [1] 8048 17 R> options("repos") $repos CRAN Local "https://cran.rstudio.com" "file://tmp/R" R> As you can see this uses the file:// notation just fine. We can also drill down: R> r <- c("CRAN"="https://cran.rstudio.com", "Local"="file://tmp/R") R> options("repos"=r[1]) R> options("repos") $repos CRAN "https://cran.rstudio.com" R> dim(AP <- available.packages()) [1] 8009 17 R> options("repos"=r[2]) R> dim(AP <- available.packages()) [1] 46 17 R> As I recall, there may have been extra complications on Windows with network drives. But if there is something (maybe documentation ?) that drat could/should do better please feel free to open an issue ticket.
