Subset the custom parameters of an operating model by simulation and projection years

## Usage

```
SubCpars(x, ...)
# S4 method for OM
SubCpars(x, sims = 1:x@nsim, proyears = x@proyears, silent = FALSE)
# S4 method for MOM
SubCpars(x, sims = 1:x@nsim, proyears = x@proyears, silent = FALSE)
```

## Arguments

- x
- ...
Arguments for method.

- sims
A logical vector of length

`x@nsim`

to either retain (TRUE) or remove (FALSE). Alternatively, a numeric vector indicating which simulations (from 1 to nsim) to keep.- proyears
If provided, a numeric to reduce the number of projection years (must be less than

`x@proyears`

).- silent
Logical to indicate if messages will be reported to console.

## Details

Useful function for running multiMSE in batches if running into memory constraints.
