plot.TWIX {TWIX} | R Documentation |
Plot an TWIX
or bootTWIX
object generated by
TWIX or bootTWIX function(s).
## S3 method for class 'TWIX': plot(x, sq = 1:length(x$trees), type = "deviance", i.plot = FALSE, size = 3, freq = TRUE, breaks = "Sturges", pch = par("pch"), ...)
x |
an object of class TWIX . |
sq |
Integer vector giving the number of trees to be plotted. |
type |
one of "deviance" , "ccr" ,"d&c" . |
i.plot |
logical. If TRUE , iplot will be used (library iplot will be required). |
size |
value for largest circle (cex ). |
freq |
logical. Should the frequence or density be plotted. |
breaks |
see histogram. |
pch |
a vector of plotting characters or symbols. |
... |
graphical parameters can be given as arguments to 'plot'. |
If type = "deviance"
:
the training deviance vs. test deviance will be plotted.
If type = "ccr"
:
the correct classification rate(CCR) for training data vs. the CCR for test data.
If type = "d&c"
:
the deviance vs. CCR for test data.
