options(Ncpus = 6L)
install.packages("remotes")
remotes::install_github("r-lib/revdepcheck")

## Used by R itself
$ revdep/run.R --preinstall RCurl XML

Pre-installation

In order to run these checks successfully on a machine without internet access, make sure to first populate the 'crancache' cache by pre-installing all packages to be tested plus a few more.

$ scl enable devtoolset-4 "revdep/run.R --preinstall blavaan"

## All packages to be tested
$ revdep/run.R --preinstall-children

• BatchGetSymbols
• datapackage.r
• GetBCBData
• GSODR
• hackeRnews
• iml
• tableschema.r
• tsfeatures
