Listing R Package Dependencies Without Installing Packages

Question

Is there a simple way to get a list of R package dependencies (all recursive dependencies) for a given package, without installing the package and it\'s dependencies? Somet

Answer 1

Another neat and simple solution is the internal function recursivePackageDependencies from the library packrat. However, the package must be installed in some library on your machine. The advantage is that it works with selfmade non-CRAN packages as well. Example:

packrat:::recursivePackageDependencies("ggplot2",lib.loc = .libPaths()[1])

giving:

 [1] "R6"           "RColorBrewer" "Rcpp"         "colorspace"   "dichromat"    "digest"       "gtable"      
 [8] "labeling"     "lazyeval"     "magrittr"     "munsell"      "plyr"         "reshape2"     "rlang"       
 [15] "scales"       "stringi"      "stringr"      "tibble"       "viridisLite"
