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.
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.
