plot.intervals.lmList
Plot lmList Confidence Intervals
Description
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 x
. The lower and upper confidence limits are connected by a line segment and the estimated coefficients are marked with a "+"
.
This is based on function dotplot()
from package lattice.
Usage
## S3 method for class 'intervals.lmList' plot(x, xlab = "", ylab = attr(x, "groupsName"), strip = function(...) strip.default(..., style = 1), ...)
Arguments
x | an object inheriting from class |
xlab, ylab | axis labels, each with a sensible default. |
strip | |
... | optional arguments passed to the |
Value
a Trellis plot with the confidence intervals on the coefficients of the individual lm
components of the lmList
that generated x
.
