How do you plot a CostSensitiveClassifier tree in

In this case I'm using the RWeka package and J48 within the Cost Sensitive Classifier function. I know with the package "party" I can plot a normal J48 tree, but not sure how to get a plot with the CSC output.

library(RWeka)

csc <- CostSensitiveClassifier(Species ~ ., data = iris, 
control = Weka_control(`cost-matrix` = matrix(c(0,10, 0, 0, 0, 0, 0, 10, 0), 
ncol = 3), 
W = "weka.classifiers.trees.J48", 
M = TRUE))

csc
CostSensitiveClassifier using minimized expected misclasification cost

weka.classifiers.trees.J48 -C 0.25 -M 2

Classifier Model
J48 pruned tree
------------------

Petal.Width <= 0.6: setosa (50.0)
Petal.Width > 0.6
|   Petal.Width <= 1.7
|   |   Petal.Length <= 4.9: versicolor (48.0/1.0)
|   |   Petal.Length > 4.9
|   |   |   Petal.Width <= 1.5: virginica (3.0)
|   |   |   Petal.Width > 1.5: versicolor (3.0/1.0)
|   Petal.Width > 1.7: virginica (46.0/1.0)

Number of Leaves  :     5

Size of the tree :  9


Cost Matrix
  0  0  0
 10  0 10
  0  0  0
plot(csc)

Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' is a list, but does not have components 'x' and 'y'

Any help would be great.

dput(csc)

        function (x) 
        {

                ind <- which(names(x) %in% substring(options,

                if (any(ind)) 
                  x[ind] <- lapply(x[ind], fun, ...)
            }
            else {
                x <- as.character(x)
                ind <- which(x %in% options)
                if (any(ind)) 
                  x[ind + 1L] <- sapply(x[ind + 1L], fun, ...)
            }
            x
        }, function (x) 
        {
            if (inherits(x, "Weka_control")) {

            }
            else {
                x <- as.character(x)
                ind <- which(x %in% options)
                if (any(ind)) 
                  x[ind + 1L] <- sapply(x[ind + 1L], fun, ...)
            }
            x
        }), data = function (mf) 
    {
        terms <- attr(mf, "terms")
        if (any(attr(terms, "order") > 1L)) 
            stop("Interactions are not allowed.")
        factors <- attr(terms, "factors")
        varnms <- rownames(factors)[c(TRUE, rowSums(factors)[-1L] > 
            0)]
        mf[, sub("^`(.*)`$", "\\1", varnms), drop = FALSE]
    }), .Names = c("control", "data")), levels = c("setosa", 
    "versicolor", "virginica"), terms = Species ~ Sepal.Length + 
        Sepal.Width + Petal.Length + Petal.Width), .Names = c("classifier", 
"predictions", "call", "handlers", "levels", "terms"), class = c("CostSensitiveClassifier", 
"Weka_meta", "Weka_classifier"))

Actually, it turns out to be pretty easy. Try

library(RWeka)
library(party)
library(partykit)


csc <- CostSensitiveClassifier(Species ~ ., data = iris, 
control = Weka_control(`cost-matrix` = matrix(c(0,10, 0, 0, 0, 0, 0, 10, 0), 
ncol = 3), 
W = "weka.classifiers.trees.J48", 
M = TRUE))

plot(as.party.Weka_tree(csc))

That gives me

The problem is, this model reports it's class as

> class(csc)
[1] "CostSensitiveClassifier" "Weka_meta"     "Weka_classifier"

and there is no method for those classes. However, there is one for "Weka_tree" which just calls as.party.Weka_tree and plots the result. I must admit I don't know the differences between a CostSensitiveClassifier tree and a J48 tree so I hope this plot is an accurate representation.
