Error in if (w_dif < specs$tol || iter == specs$maxiter) break

[TKsh6]

Hi, When I used plspm to build a model for the microbiome, I met this problem，

Error in if (w_dif < specs$tol || iter == specs$maxiter) break : 
  missing value where TRUE/FALSE needed

Then I checked if there were any NAs in my data, but there were none of them. So how can I do to fix this? Hope you can help me to solve this. yours,tk
