update {mrgsolve} | R Documentation

## Update the model object

### Description

After the model object is created, update various attributes.

### Usage

    ## S4 method for signature 'mrgmod'
    update(object, ..., merge = TRUE, open = FALSE, data = NULL, strict = TRUE)

    ## S4 method for signature 'omegalist'
    update(object, y, ...)

    ## S4 method for signature 'sigmalist'
    update(object, y, ...)

    ## S4 method for signature 'parameter_list'
    update(object, .y, ...)

### Arguments

`object` | a model object
`...` | named items to update
`merge` | logical indicating to merge (rather than replace) new and existing attributes
`open` | logical; used only when merge is `TRUE` and parameter list or initial conditions list is being updated; if `FALSE`, no new items will be added; if `TRUE`, the parameter list may expand.
`data` | a list of items to update; this list is combined with any items passed in via `...`
`strict` | if `TRUE`, then an error will be generated if there is attempt to update a non-existent item
`y` | another object involved in update
`.y` | data to update
