The modified parameter set.

Examples

params <- list(lambda = penalty(), alpha = mixture(), `rand forest` = mtry())
pset <- parameters(params)
pset
#> Collection of 3 parameters for tuning
#> 
#>   identifier    type    object
#>       lambda penalty nparam[+]
#>        alpha mixture nparam[+]
#>  rand forest    mtry nparam[?]
#> 
#> Parameters needing finalization:
#>    # Randomly Selected Predictors ('rand forest')
#> 
#> See `?dials::finalize` or `?dials::update.parameters` for more information.
