R: Plot lmList Confidence Intervals

plot.intervals.lmList {nlme}

R Documentation

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 "+". The Trellis function dotplot is used in this method function.

Usage

## S3 method for class 'intervals.lmList'
plot(x, ...)

Arguments

`x`	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 `x`.
`...`	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 x.
