Test radiomic signature by Cox regression model

test_radiomic_signature(
  rdr = NULL,
  surv_obj = NULL,
  signature = NULL,
  signature_rdr = NULL,
  which_data = "scaled"
)

`rdr`	A RadAR object (class `SummarizedExperiment`).
`surv_obj`	An object of class `Surv`.
`signature`	(character) vector of radiomic features defining the signature.
`signature_rdr`	RadAR object (class `SummarizedExperiment`) obtained by `do_feature_selection`. Required to test a model generated using glmnet-cox or glmnet-binom.
`which_data`	(character) Which data use to compute concordance index. It can be one of the following: "normal", "scaled", "normalized".

In case of mRMR, hcl and pca methods, the function returns the results of the cox regression model, including the concordance index. In case of glmnet-cox method, the function returns a list of two elements, including 1) the prediction of the glmnet model on the new data and 2) the computation of concordance index.
