Classifly problems
...I paste the code I am using:
library(MASS)
Tumor <- c(rep("MM",20),rep("GBM",18),rep("LGG",17))
data.lda <- lda(data,Tumor)
data.ld <- predict(data.lda)
data.ldd <- data.frame(data.ld$x,data.ld$class)
library(rggobi)
data.g <- ggobi(data.ldd)
library(classifly)
generate_classification_data(data.lda,data,method="grid",n=100000)
Could you help me?
Best regards,
Dani

classifly 0.2.2
The classifly package uses rggobi to visualise classification
boundaries in high-dimensions. Given p-dimensional training data
containing d groups (the design space), a classification algorithm
(classifier) predicts which group new data belongs to. Generally the
input to these algorithms is high dimensional, an...

How to draw the decision boundaries for LDA and Rpart object
Hello useR,
Could you please tell me how to draw the decision boundaries in a scatterplot of the original data for a LDA or Rpart object.
For example:
> library(rpart)
>fit.rpart <- rpart(as.factor(group.id)~., data=data.frame(Data) )
How can I draw the cutting lines on the orignial Data?
Or is there any built in functions that can read the rpart object 'fit.rpart' to do

LDA decission boundaries
Hello,
I would like to plot the results of a LDA analysis plotting the
discriminant scores with the decission boundaries on it with rggobi. I
have GGobi already installed on my computer. I have three classes, so
the plot would be LD1xLD2 plus the decission boundaries. Here there is
the code I use make the plot:
library(MASS)
data <- zgcppr273K.pca$x[,1:7]
Tumor <-
