Error in loadNamespace(x) : there is no package called ‘visNetwork’

I just reinstalled pkgcheck and upon attaching the library I get an error message:

library(pkgcheck)
pkgcheck::pkgcheck()
Error in loadNamespace(x) : there is no package called ‘visNetwork’

The solution is in the message: You need to install that package too. It's a suggested dependency, not an important, so may not be automatically installed, depending on how you configure your install process. But installing it will fix everything anyway.
