Perf function: error in solve.default(Sr): system is computationally singular

Hi again @hchen8, so far so good! :slight_smile:

Then it could be due to:

  • Too many missing or zero values. nearZeroVar() can be used to handle this, either externally or internally in the pls function.
  • Too many components (empty residual matrices)
  • Variables that are highly correlated/nearly the same (multi collinearity)

Let me know if any of these solved the problem.
