## S3 method for class 'ranef.mjoint'
plot(x, ...)

Arguments

x

an object inheriting from class ranef.mjoint, representing the estimated random effects for the mjoint object from which it was produced.

...

additional arguments; currently none are used.

Value

an object inheriting from class ggplot, which displays a trellis plot with a separate panel for each effect, showing a dotplot (with optional error bars indicating approximate 95% prediction intervals if the argument postVar=TRUE is set in the call to ranef) for each subject (by row).
