Downloads a list of tgz files from a list of repos and unpacks them

Usage

download_distribute(
  files,
  repositories = list(`/p/projects/rd3mod/inputdata/output` = NULL),
  modelfolder = ".",
  additionalDelete = NULL,
  debug = FALSE,
  stopOnMissing = FALSE
)

Value

Information about the download process in form of a data.frame with data sets as row names and repositories (where it was downloaded from) and corresponding md5sum as columns

Arguments

files: a vector of files containing input data, if a file is no .tgz it will be downloaded and not unpacked
repositories: a list of repositories (please pay attention to the list format!) in which the files should be searched for. Files will be searched in all repositories until found, always starting with the first repository in the list. The argument must have the format of a named list with the url of the repository as name and a corresponding list of options such as username or password to access the repository as value. If no options are required the value has to be NULL. (e.g. list("ftp://my_pw_protected_server.de/data"=list(user="me",password=12345), "http://free_server.de/dat"=NULL))
modelfolder: main model folder
additionalDelete: information which additional data should be deleted before new data are downloaded and distributed
debug: switch for debug mode with additional diagnostic information
stopOnMissing: Boolean passed along to download_unpack() to stop if any file in files could not be downloaded. Off (FALSE) by default.
