# Create example hyperdesign
d1 <- multidesign(matrix(rnorm(10*20), 10, 20),
                  data.frame(subject=1, condition=rep(c("A","B"), 5)))
d2 <- multidesign(matrix(rnorm(10*20), 10, 20),
                  data.frame(subject=2, condition=rep(c("A","B"), 5)))
d3 <- multidesign(matrix(rnorm(10*20), 10, 20),
                  data.frame(subject=3, condition=rep(c("A","B"), 5)))
hd <- hyperdesign(list(d1, d2, d3))

# Keep only condition A
subset_hd <- subset(hd, condition == "A")
