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`.
