print.summary.pdMat {nlme} | R Documentation

## Print a summary.pdMat Object

### Description

The standard deviations and correlations associated with the positive-definite matrix represented by `object` (considered as a variance-covariance matrix) are printed, together with the formula and the grouping level associated `object`, if any are present.

### Usage

    ## S3 method for class 'summary.pdMat':
    print(x, sigma, rdig, Level, resid, ...)

### Arguments

`x` | an object inheriting from class `summary.pdMat`, generally resulting from applying `summary` to an object inheriting from class `pdMat`.
`sigma` | an optional numeric value used as a multiplier for the square-root factor of the positive-definite matrix represented by `object` (usually the estimated within-group standard deviation from a mixed-effects model). Defaults to 1.
`rdig` | an optional integer value with the number of significant digits to be used in printing correlations. Defaults to 3.
`Level` | an optional character string with a description of the grouping level associated with `object` (generally corresponding to levels of grouping in a mixed-effects model). Defaults to NULL.
`resid` | an optional logical value. If `TRUE` an extra row with the `"residual"` standard deviation given in `sigma` will be included in the output. Defaults to `FALSE`.
`...` | optional arguments passed to `print.default`; see the documentation on that method function.
