Attribute Combinations
One possible way
library(tidyr)
dat1 <- structure(list(V1 = c("A", "A", "A", "A", "A", "A", "A", "A",
"A", "A"), V2 = c("A", "B", "A", "A", "A", "B", "C", "C", "B",
"C"), V3 = c("B", "C", "D", "B", "B", "C", "B", "B", "C", "C"
)), class = "data.frame", row.names = c(NA, -10L))
dat2 <- unite(dat1, att, V1, V2, V3, sep = ",")
prop.table(table(dat2$att))
A,A,B A,A,D A,B,C A,C,B A,C,C
0.3 0.1 0.3 0.2 0.1

Looking for a function or some guidance for obtaining the percentage of
attribute combinations, for example
V1 V2 V3
A A B
A B C
A A D
A A B
A A B
A B C
A C B
A C B
A B C
A C C
Results
A,A,B 0.30
A,B,C 0.30
A,A,D 0.10
A,C,B 0.20 etc
Sincerely
