When trying to install RInno and run install_inno() the following issue appears:

> install_inno()
Error in split_chain(match.call(), env = env) : 
  could not find function "split_chain"

From searching for a resolution to this issue, I came across another github R community with the same issue, furniture

It was advised that the error results from the updated magrittr package that is being referenced by the RInno package. TysonStanley Comment

Not sure what the exact fix is, but the furniture package has made an update in their developmental version to fix this issue, which may be of help when solving it for the RInno package.
