convertHub: Convert old Hub to new Hub structure

In Bioconductor/AnnotationHub: Client to access AnnotationHub resources

Convert old Hub to new Hub structure

Description

The Hub class was updated to utilize BiocFileCache to allow for file level caching control. This update changed the way files were stored and named. As a convenience for AnnotationHub and ExperimentHub we have provided this helper function to try to re-download files and add them into the BiocFileCache tracking database.

Usage

convertHub(oldcachepath=NULL,
           newcachepath=NULL,
           hubType=c("AnnotationHub", "ExperimentHub"),
           proxy=getAnnotationHubOption("PROXY"),
           max.downloads=getAnnotationHubOption("MAX_DOWNLOADS"),
           force=FALSE, verbose=TRUE)

Arguments

oldcachepath	character(1) complete file path location of the old hub to be converted. If left as NULL, will use the default path of the old code, which for unix systems was in a user's home directory "~\" and for windows users was in a user's AppData directory "~\AppData".
newcachepath	character(1) complete file path to the new location for the cache. If left as NULL, will use the new default path which utilizes the rappdir::user_cache_dir to deterime the appropriate caching location.
hubType	Either AnnotationHub or ExperimentHub. By default assumes AnnotationHub.
proxy	proxy connection allowing Internet access, usually through a restrictive firewall. Default: NULL.
max.downloads	numeric(1). The integer number of downloads allowed before triggering a warning. This is to help avoid accidental download of a large number of AnnotationHub members
force	logical(1). Force re-download of a resource rather than using a cached version.
verbose	logical(1). Print out status messages.

Value

character(1). File path of new cache location. If verbose also prints status messages for downloading files and any files that were not redownloaded.
