Error when weighting

[statzhero]

I get the following error message when running a basic example. I believe all variables are well-behaved and have no missing data. Sorry about the lack of details but maybe there's an obvious answer.

weightit(treatment ~ rev_log,
                    data = d,  
                    method = "ebal")

Error in if (all(as.character(unique.treat.bin) == as.character(unique.treat))) { : 
  missing value where TRUE/FALSE needed

This is actually really surprising so I'm not sure what could be going on. Would you be willing to send me the data or a different reproducible example? Is the treatment binary? Does this happen when using other methods besides "ebal"? Is d a tibble (e.g., resulting from a function in haven)?

Can you try this and let me know if it helps?

dta <- structure(
  list(treatment = c(FALSE, FALSE, TRUE, TRUE), 
       rev_log_match = c(17.8267157645103, 16.4479714107295, 16.9735477181105, 18.1387239441378)), 
          row.names = c(NA,-4L), 
          groups = structure(
            list(treatment = c(FALSE, TRUE), 
                .rows = structure(list(1:2, 3:4), 
                ptype = integer(0),
                class = c("vctrs_list_of","vctrs_vctr", "list"))), 
            row.names = c(NA, -2L),
            class = c("tbl_df","tbl", "data.frame"), .drop = TRUE), 
       class = c("grouped_df", "tbl_df", "tbl", "data.frame"))

WeightIt::weightit(treatment ~ rev_log_match, data = dta)

Thank you! It turns out that is because the treatment was a logical vector. If you make it 0s and 1s you should not receive this error. Let me know if that works. I'm fixing this now so that logical vectors should work fine.
