[R] svm

[AbouEl-Makarim Aboueissa]

Dear All:


I am trying to use the R function "svm" with  "type =C-classification" ,
but I got the following error message


SVM.Model1 <- svm(type ~ ., data=my.data.x1x2y, *type='C-classification'*,
kernel='linear',scale=FALSE)

*Error in eval(predvars, data, env) : object 'type' not found*


I am wondering if I should install a specific R package(s).



*Here is my codes:*


feature.x1 <- c(0.25,0.5,1,1,1.5,2,2.25,2.5,2,1,3,   5,3.75,
1,3.5,4,4,5,5.5,6,6,6.5)

length(feature.x1)



feature.x2 <- c(2,3.5,1,2.5,1.75,2,1.75,1.5,2.5,1,1,
 3.5,3.5,5.8,3,4,4.5,5,4,1,4,3)

length(feature.x2)


y <- c(rep(-1,11), rep(1,11))

typey<-as.factor(y)


my.data.x1x2y <- data.frame(feature.x1, feature.x2, typey)

my.data.x1x2y



install.packages("e1071")

library(e1071)



SVM.Model1 <- svm(type ~ ., data=my.data.x1x2y, type='C-classification',
kernel='linear',scale=FALSE)

plot(my.data.x1x2y[,-3],col=(typey+3)/2, pch=18, xlim=c(-1,6), ylim=c(-1,6))

box(lwd = 2, col="darkgreen")







with many thanks
abou
