Market Basket Analysis in R

Given below are few observations from my data set

structure(list(p1 = c(1L, 0L, 0L, 0L, 0L, 1L, 0L, 1L, 1L, 0L), 
    p2 = c(1L, 0L, 1L, 1L, 1L, 0L, 0L, 0L, 1L, 0L), p3 = c(1L, 
    1L, 1L, 1L, 1L, 1L, 1L, 0L, 0L, 0L), p4 = c(1L, 1L, 1L, 1L, 
    1L, 0L, 1L, 0L, 0L, 0L)), .Names = c("p1", "p2", "p3", "p4"
), row.names = c(NA, -10L), class = "data.frame")

The column name depict a type of skill in a project required by 1 in front of that project row. I want to create a common basket of skills which occur together for maximum number of projects. Is there any way of doing market basket analysis on the given data in R? Or any way to solve the above problem.


Check out the arules package:

trans <-  as(as.matrix(df), "transactions")
rules <- apriori(trans, parameter = list(supp = 0.01, conf = 0.1, target = "rules", minlen=2))
inspect(sort(rules[1:5], by="confidence"))
#   lhs     rhs  support confidence      lift
# 1 {p1} => {p2}     0.2  0.5000000 1.0000000
# 2 {p1} => {p3}     0.2  0.5000000 0.7142857
# 3 {p2} => {p1}     0.2  0.4000000 1.0000000
# 4 {p1} => {p4}     0.1  0.2500000 0.4166667
# 5 {p4} => {p1}     0.1  0.1666667 0.4166667
