Boxplot for 'ps' objects
This function produces a collection of diagnostic plots for ps objects.
## S3 method for class 'ps' boxplot(x, subset = NULL, color = TRUE, time = NULL, ...)
x |
A 'ps' object |
subset |
If multiple 'stop.method' rules were used in the 'ps()' call, 'subset' restricts the plots of a subset of the stopping rules that were employed. This argument expects a subset of the integers from 1 to k, if k 'stop.method's were used. |
color |
If 'FALSE', a grayscale figure will be returned. |
time |
For use with iptw fits. |
... |
Additional arguments that are passed to boxplot function, which may bepassed to the underlying 'lattice' package plotting functions. |
