truthTable in Rstudio Error: incorrect outcome specification

Question

I was trying to do a QCA analysis of sufficeny in RStudio 4.1.3. using truthTable command. By running the code i get Error: wrong outcome specification. The outcome is written correctly. When I do an analysis of necessity with superSubset code everything works fine. Everything is coded numeric but it does not work with bivariate callibration either.

> ttCO21 <- truthTable( data = mydata, outcome = "CO21",
+                          conditions = "GENDG1, FDI1, GDP1",
+                          sort.by="incl, n", show.cases = TRUE, complete = TRUE)

**Error: Incorrect outcome specification.**

Answer 1

I had the same issue today and the solution was to delete any unnecessary columns (or create a new dataframe). I left only the calibrated conditions and outcome, because when I found this error, the raw data was in the same df, even if was not using it in the truthTable() command.

Answer 2

you can try "comma" instead of "dot" (in “decimal") when you import file

Answer 3

Because of the 3 hours i wasted on this problem i'll share my situation and solution. I had the exact same problem. creating a new df did not help, nor did removing unnecessary colums (wouldn't make sense anyway). Completely reinstalling en reloading the QCA package did work for me. Hope this helps someone.
