diagnostic and confidence-interval plots for lmList
fits
## S3 method for class 'lmList4' plot(x, form, abline, id, idLabels, grid, ...) ## S3 method for class 'lmList4.confint' plot(x, y, order, ...)
x |
an object inheriting from class |
y |
ignored: for agreement with generic method |
form |
an optional formula specifying the desired type of
plot. Any variable present in the original data frame used to obtain
|
abline |
an optional numeric value, or numeric vector of length two. If given as a single value, a horizontal line will be added to the plot at that coordinate; else, if given as a vector, its values are used as the intercept and slope for a line added to the plot. If missing, no lines are added to the plot. |
id |
an optional numeric value, or one-sided formula. If given as
a value, it is used as a significance level for a two-sided outlier
test for the standardized residuals. Observations with
absolute standardized residuals greater than the 1 - value/2
quantile of the standard normal distribution are identified in the
plot using |
idLabels |
an optional vector, or one-sided formula. If given as a
vector, it is converted to character and used to label the
observations identified according to |
grid |
an optional logical value indicating whether a grid should
be added to plot. Default depends on the type of Trellis plot used:
if |
order |
which coefficient to order the results by |
... |
optional arguments passed to the Trellis plot function. |
