I am conducting a mendelian randomization study, and as an exposure I have hundreds of triats. The code below is part of a loop that iterates over these triats.

  # Apply Clumping 
  SeqId_data <- ieugwasr::ld_clump_local (
  SeqId_data,
  clump_p = 1,
  clump_r2 = r2,
  clump_kb = 10000,
  plink_bin = genetics.binaRies::get_plink_binary(), 
  bfile= "/path/to/reference/EUR" )

And am getting this output

Any idea what might be the problem?

Thank you

Plink said

Warning: No significant --clump results.  Skipping.

And then R said it can't open the results file from running Plink. Which won't exist, because Plink already said there were none.
