catboost dependency

[laresbernardo]

When installing,catboost wasn't found. Maybe add this step into the README file? O remove from Imports.

Also, after installing and refreshing my R session, I'm getting this error with the titanic example:

Error in library.dynam(lib, package, package.lib) :

@laresbernardo I had to visit the Catboost website and follow the instructions to install: https://catboost.ai/docs/installation/r-installation-binary-installation.html

[kozaka93]

Thank you. The problem comes from, catboost library has not been yet available in CRAN. So, you can follow this link: https://catboost.ai/docs/concepts/r-installation.html to install catboost.

@laresbernardo You can try to run the following codes to install for MacOS:

devtools::install_url('https://github.com/catboost/catboost/releases/download/v0.26.1/catboost-R-Darwin-0.26.1.tgz', INSTALL_opts = c("--no-multiarch", "--no-test-load"))

[laresbernardo]

Thanks @mcavs That did the trick :)
