Create a mixed effects model from an mmkin row object
mixed(object, ...) # S3 method for mmkin mixed(object, method = c("none"), ...) # S3 method for mixed.mmkin print(x, digits = max(3, getOption("digits") - 3), ...)
Arguments
| object | An mmkin row object |
|---|---|
| ... | Currently not used |
| method | The method to be used |
| x | A mixed.mmkin object to print |
| digits | Number of digits to use for printing. |
