refresh {renv} | R Documentation |
Query the active R package repositories for available packages, and update the in-memory cache of those packages.
refresh()
Note that R also maintains its own on-disk cache of available packages,
which is used by available.packages()
. Calling refresh()
will force
an update of both types of caches. renv
prefers using an in-memory
cache as on occasion the temporary directory can be slow to access (e.g.
when it is a mounted network filesystem).
A list of package databases, invisibly – one for each repository currently active in the R session. Note that this function is normally called for its side effects.
## Not run: # check available packages db <- available.packages() # wait some time (suppose packages are uploaded / changed in this time) Sys.sleep(5) # refresh the local available packages database # (the old locally cached db will be removed) db <- renv::refresh() ## End(Not run)
