Description Usage Arguments Value Author(s)

Given a numeric vector, a plot of four panels is drawn: 1) fitted mixture distribution 2) transformed expression against original expression 3) histogram of original expression 4) progression of log-likelihood during the fit

1 2	em.draw(vec, cl, threshold=0.0001) #em.draw(vec, cl=1-metastasis, threshold=0.0001)

`vec`	A numeric vector, especially a particular row of expression matrix
`cl`	A vector of 0s and 1s. Use 1 for normal phenotype and 0 for non-normal phenotype. If left blank, all samples will be labeled as normal phenotype. Normal component of mixture is estimated using samples with normal phenotype only. POE for samples with non-normal phenotype will be calculated after EM algorithm finishes ML estimation.
`threshold`	Crieterion for convergence in likelihood.
