slm.methods {SparseM} | R Documentation |
Summarize, print, and extract objects from slm
objects.
summary.slm(object, correlation, ...) summary.mslm(object, ...) print.slm(x, digits, ...) print.summary.slm(x, digits, symbolic.cor, signif.stars, ...) fitted.slm(object, ...) residuals.slm(object, ...) coef.slm(object, ...)
object,x |
object of class slm . |
digits |
minimum number of significant digits to be used for most numbers. |
symbolic.cor |
logical; if TRUE , the correlation of coefficients
will be printed. The default is FALSE |
signif.stars |
logical; if TRUE , P-values are additionally encoded
visually as ``significance stars'' in order to help scanning
of long coefficient tables. It defaults to the
`show.signif.stars' slot of `options'. |
correlation |
logical; if TRUE , the correlation matrix of the
estimated parameters is returned and printed. |
... |
additional arguments passed to methods. |
print.slm
and print.summary.slm
return invisibly.
fitted.slm
, residuals.slm
, and coef.slm
return the corresponding components of the slm
object.
