An error occurs when I call the function prior_flowclust:

Error in if (class(try(solve(cov_mat), silent = TRUE)) == "try-error") { : the condition has length > 1

There was no error in R 4.1.3, but since R 4.2.0 I cannot call prior_flowclust without error. I guess the last if clause in prior_flowclust containing try has not been adapted to the new vectorized version of try.
