Examples

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

# Get data from all blocks
all_data <- xdata(hd)

# Get data from block 1
block1_data <- xdata(hd, block=1)
