agep {wateRmelon} | R Documentation |
Predict age of samples using Horvaths Coefficients
agep(betas, coeff=NULL, method=c('horvath','hannum') ,...)
betas |
Matrix of betas or MethyLumiSet or MethylSet object. |
coeff |
If NULL, will default to Horvaths coefficients. Otherwise can be supplied with vector of own coefficients with an intercept as first element. |
method |
currently either "horvath" or "hannum". If using "hannum" remember to call data(hannumCoef) before analysis and supply coeff with the hannum coefficients, otherwise will default to "horvath". |
... |
To pass to arguments to downstream functions to specify adult.age |
Returns matrix of predicted ages per sample.
