I am trying to fit classifier using SVM for a dataset with multiple variable.
r-code
attach(wifiLocDat) x <- subset(wifiLocDat, select=-Loc3) y <- Loc3 x[y==1 ,] <- x[y==1,] + 1 wifiDat <- data.frame(x=x,y=as.factor(y)) svmfit <- svm(Loc3~., data=wifiLocDat, kernel="linear", cost=1, scale=FALSE) plot(svmfit,wifiDat)
Error code:
Error in plot.svm(svmfit, wifiDat) : missing formula.
Sample Data
WiFi1 WiFi2 WiFi3 WiFi4 WiFi5 WiFi6 WiFi7 Loc3 1 -64 -56 -61 -66 -71 -82 -81 FALSE 2 -68 -57 -61 -65 -71 -85 -85 FALSE 3 -63 -60 -60 -67 -76 -85 -84 TRUE 4 -61 -60 -68 -62 -77 -90 -80 FALSE 5 -63 -65 -60 -63 -77 -81 -87 TRUE 6 -64 -55 -63 -66 -76 -88 -83 FALSE
