Examples

# construct annmatrix object
x <- matrix(rnorm(20*10), 20, 10)

coldata <- data.frame(group  = rep(c("case", "control"), each = 5),
                      gender = sample(c("M", "F"), 10, replace = TRUE))

rowdata <- data.frame(chr = sample(c("chr1", "chr2"), 20, replace = TRUE),
                      pos = runif(20, 0, 1000000))

X <- annmatrix(x, rowdata, coldata)

print(X)
print(X, 10, 5)
print(X, 2, 2)

# also works with a list-based matrix
x <- matrix(list(mtcars, iris3, USAccDeaths, rivers), ncol=2)
print(x)
X <- annmatrix(x)
print(X)
