Can not get chi squared or write.xlsx

[gjones2000]

Hello,

When I try to perform part 2_Feature Selection. I get the error 'Error in do.call : could not find function "chi.squared". However, R 3.6.3 doesn't have this as a package.

Secondly, when I try to perform 5_Performance Evaluation Model. I get the error 'Error in do.call : could not find function "write.xlsx". However, R 3.6.3 also doesn't have this as a package.

Please can somebody help. I am trying to learn this from scratch for my dissertation due in 2 months.

Thank you!

Hi, Did you install Java Runtime Environment (https://java.com/en/download/manual.jsp). If you did not install, install both 32 and 64 bit version.
