Upgrade MizerParams object from earlier mizer versions

Occasionally during the development of new features for mizer, the MizerParams object gains extra slots. MizerParams objects created in older versions of mizer are then no longer valid in the new version because of the missing slots. This function adds the missing slots and fills them with default values.

upgradeParams(params)

Arguments

params	An old MizerParams object to be upgraded

Value

The upgraded MizerParams object

Details

Uses newMultispeciesParams() to create a new MizerParams object using the parameters extracted from the old MizerParams object.

If you only have a serialised version of the old object, for example created via `saveRDS()`, and you get an error when trying to read it in with `readRDS()` then unfortunately you will need to install the old version of mizer first to read the params object into your workspace, then switch to the current version and then call `upgradeParams()`. You can then save the new version again with `saveRDS()`.
