    summary(object, what = c("all", "validation", "training"),
            digits = 4, print.gap = 2, ...)
    ## S3 method for class 'mvr'
    print(x, ...)
    ## S3 method for class 'mvrVal'
    print(x, digits = 4, print.gap = 2, ...)

### Arguments

`x, object` | an `mvr` object
`what` | one of `"all"`, `"validation"` or `"training"`
`digits` | integer. Minimum number of significant digits in the output. Default is 4.
