How to coerce a truth table into a dataset or in tibble

Question

I have a dataset where I am training on to coerce as dataset (foundable in the onòy in SetMethods package)

library(QCA)
library(SetMethods)

data(SCHF)

# Get the truth table for the presence of the outcome:

TT_y <- truthTable(SCHF, outcome = "EXPORT",
                   conditions = c("EMP","BARGAIN","UNI","OCCUP","STOCK", "MA"),
                   incl.cut = .9,
                   complete = TRUE,
                   PRI = TRUE,
                   sort.by = c("out", "incl", "n"))

what I would like to to is to coerce this object into a dataset. This is my failing trial

table = as.data.table(TT_y)
table

Would you have some possible alternative? Thanks

Answer 1

We could extract the tt data frame directly from the object returned by truthTable. We will, however, need to remove the rows where n == 0 to obtain what you're after.

library(QCA)

tT <- truthTable(LC, "SURV")$tt # Extract data frame from object

tT[tT$n > 0, ] # Show the relevant rows

Output:

   DEV URB LIT IND STB OUT n incl PRI       cases
1    0   0   0   0   0   0 3    0   0    GR,PT,ES
2    0   0   0   0   1   0 2    0   0       IT,RO
5    0   0   1   0   0   0 2    0   0       HU,PL
6    0   0   1   0   1   0 1    0   0          EE
22   1   0   1   0   1   1 2    1   1       FI,IE
23   1   0   1   1   0   0 1    0   0          AU
24   1   0   1   1   1   1 2    1   1       FR,SE
31   1   1   1   1   0   0 1    0   0          DE
32   1   1   1   1   1   1 4    1   1 BE,CZ,NL,UK

Data:

The data used here is the Lipset binary crisp data used in the first example in the documentation of QCA::truthTable. I cannot find the SCHF-dataset.

Update: I've found the dataset (and updated OP). Same approach, new filtering :-)

library(SetMethods)
library(QCA)

data(SCHF)

tT <- TT_y$tt
tT[order(tT$incl, decreasing = TRUE), 1:10]

Output:

   EMP BARGAIN UNI OCCUP STOCK MA OUT  n              incl                PRI
