R: Check if glmnet should call cox.path

use.cox.path {glmnet} | R Documentation

## Check if glmnet should call cox.path

### Description

Helper function to check if glmnet() should call cox.path().

### Usage

    use.cox.path(x, y)

### Arguments

`x` | Design matrix.
`y` | Response variable.

### Details

For `family="cox"`, we only call the original coxnet() function if (i) x is not sparse, (ii) y is right-censored data, and (iii) we are not fitting a stratified Cox model. This function also throws an error if y has a "strata" attribute but is not of type "stratifySurv".

### Value

TRUE if cox.path() should be called, FALSE otherwise.
