I am trying to build a classifier using SVM and I have 23 independent
variables and 1 response.
I want to check the classification ac curacies of each independent
variables. I did this without any problem.
Now, I want to check the all possible combinations for any two variables
using following script:
> data=read.csv('Relapse_recoded.csv', header=TRUE, sep=',');
> y=data[,2];
> library(e1071);
> for (i in 3:25){
+ j=i+1
+ model=svm(y,data[,c(i,j)], type='C', kernel='linear',
cross=110)
+ m=summary(model)
+ print(i)
+ print(j)
+ print(m)
+ }
*Error in scale(newdata[, object$scaled, drop = FALSE], center
object$x.scale$"scaled:center", :
(subscript) logical subscript too long*
Does anyone know why is this error message??
Thank you in advance
