plot(x, breaks = 25, ...)

Examples

if (FALSE) { # \dontrun{
# Generate example data
n <- 200
p <- 10
Z <- matrix(rnorm(n * p), n, p)
T <- rep(c(1, 2), each = n/2)

# Run fast classification permutation test
result <- fastcpt(Z, T, class.methods = "forest", perm.N = 100)

# Plot the results
plot(result)
} # }
