Hello, I'm responsible for maintaining a mirrored internal CRAN repository for my organization. We have a script that uses the miniCRAN library to add and update packages within the repository and since the repository is stored on a network drive I have to use UNC paths when calling miniCRAN functions such as this:
updatePackages(path = '\\\\my-network-drive.net\\repos\\packages', ...) updatePackages function in turns call pkgAvail, another miniCRAN function, which calls available.packages and then read.dcf function. However I discovered that this line in available.packages transforms the UNC path to a form that read.dcf can't use: if (startsWith(repos, "file:///")) {tmpf <- paste0('/', substring(repos, 8L), "/PACKAGES") This line transforms my UNC path to //\\\\my-network-drive.net\\repos\\packages, which read.dcf can't use. During debugging I found that pkgAvail transformed my UNC path to 'file:///\\\\ my-network-drive.net\\repos\\packages' and that is the path being passed to available.packages. To fix my issue I re-defined my own available.packages function and changed the line to: if (startsWith(repos, "file:///")) {tmpf <- paste0('/', substring(repos, 10L), "/PACKAGES") This way the UNC path being passed to read.dcf will be '/\\my-network-drive.net\\repos\\packages', which read.dcf can use. I'm wondering if similar changes can be made in the available.packages function for the next R release to automatically detect UNC paths and modify it so that it can work with UNC paths.
