Error in tab_list[[index_optimal]]: attempt to select less than one element in get1index

[CharlesARoy]

Just to start the conversation, I was unable to resolve the following bug when attempting to use Tune_ConQuR(). The command I ran was:

result_tuned = Tune_ConQuR(
       tax_tab = Sample_Data,
       batchid = batchid,
       covariates = covar,
       batch_ref_pool = c("0", "1", "2", "3"),
       logistic_lasso_pool = c(T, F),
       quantile_type_pool = c("standard", "lasso", "composite"),
       simple_match_pool = c(T, F),
       lambda_quantile_pool = c(NA, "2p/n", "2p/logn"),
       interplt_pool = c(T, F),
       frequencyL = 0,
       frequencyU = 1,
       cutoff = 0.1,
       delta = 0.4999,
       taus = seq(0.005, 0.995, by = 0.005),
       num_core = 10
     )

And after running for over 2 days, it output the following error:

Error in tab_list[[index_optimal]] :
  attempt to select less than one element in get1index

The error appears to come from this line and presumably there's an edge case from line 248 that causes index_optimal to not be a valid positive integer, for whatever reason.

Thanks for pointing it out. It would be better if you could provide sample data for us to reproduce the error. We will look into this issue.

Thank you @wdl2459! It's great to hear from you! I'd love to get your input on #28 if you have a chance.

Also #20 describing another issue I emailed you about seems to be easy to fix. The forked repo only changed a few lines of code and I can confirm that those changes worked.

Thanks for confirming that changes in the forked repo work. We will incorporate them into the software.
