Hello,
I am trying to explore a classification with GGobi. I am trying to
generate additional data according to the model so I can draw the
decision boundaries on the GGobi plot. The problem is that I always get
the same error: Error in predict.lda(model,data): wrong number of
variables, even if I know that I used the same number of variables for
the model generation (6) and for the additional data generation (6
also). 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
