dataset loads/reads "twice" into gfci.discrete

[kingfish777]

When I load a dataset into rcausal/gfci.discrete, it seems to load twice, effectively taking twice as long ===>

`> rcausal::gfci.discrete(dat) node_names: ade value: [1] 0 1

node_names: medication value: [1] 0 1

node_names: diabetes_mellitusCOMMA_nonHYPHENinsulinHYPHENdependent value: [1] 0 1

node_names: ligation value: [1] 0 1

node_names: insulin_sensitivity value: [1] 0 1

node_names: ade value: [1] 0 1

node_names: medication value: [1] 0 1

node_names: diabetes_mellitusCOMMA_nonHYPHENinsulinHYPHENdependent value: [1] 0 1

node_names: ligation value: [1] 0 1

node_names: insulin_sensitivity value: [1] 0 1 `

Going to try PC and FGeS after this. --Kingfish777
