appRIVER(dataInput, pseudoc = 50, theta_init = matrix(c(0.99, 0.01, 0.3,
  0.7), nrow = 2), costs = c(100, 10, 1, 0.1, 0.01, 0.001, 1e-04),
  verbose = FALSE)

`dataInput`	An object of ExpressionSet class which contains input data required for all functions in RIVER including genomic features, outlier status, and N2 pairs.
`pseudoc`	Pseudo count.
`theta_init`	Initial values of theta.
`costs`	Candidate penalty parameter values for L2-regularized logistic regression.
`verbose`	Logical option for showing extra information on progress.

A list which contains subject IDs, gene names, posterior probabilities from GAM and RIVER, and estimated parameters from RIVER with used hyperparameters.

To input a vector of candidate penalty values makes glmnet faster than to input a single penalty value
