  • 52.0 corresponds to Java 8 ([see here](https://stackoverflow.com/questions/9170832/list-of-java-class-file-format-major-version-numbers)). Are you running an even older version? – fracpete Jan 12 '22 at 09:24
  • It looks like you're fairly new to SO; welcome to the community! If you want great answers quickly, it's best to make your question reproducible. This includes the code leading up to this error. Check it out: [making R reproducible questions](https://stackoverflow.com/q/5963269). That being said, if you received this error after attempting to install this package, you do not have the dependencies installed. The `FSelector` package depends on two other packages: `RWekajars` and `RWeka`. Typically dependencies install automatically. You can install them separately, though. – Kat Jan 20 '22 at 19:31
  • Please provide enough code so others can better understand or reproduce the problem. – Kat Jan 20 '22 at 19:32
