A Trellis dot-plot of the confidence intervals on the linear model
coefficients is generated, with a different panel for each
coefficient. Rows in the dot-plot correspond to the names of the
lm
components of the
lmList object used to produce
object
. The lower and upper confidence limits are connected by
a line segment and the estimated coefficients are marked with a
+
. The Trellis function
dotplot is used in this method
function.
USAGE:
plot(object, ...)
REQUIRED ARGUMENTS:
object
an object inheriting from class
intervals.lmList,
representing confidence intervals and estimates for the
coefficients in the
lm components of the
lmList object
used to produce
object.
OPTIONAL ARGUMENTS:
...
optional arguments passed to the Trellis
dotplot
function.
VALUE:
a Trellis plot with the confidence intervals on the coefficients of
the individual
lm components of the
lmList that
generated
object.
