svm - How to not hardcode the values in the model in R -


in r svm model, how can change predicted variable not being hardcoded in model itself, rather variable name can have different value.

svmmodel <- svm(sr~., data = dataset)

here how can change sr~. variable can have sr or someother value needs predicted

you can build formuals dynamically in different ways. 1 way use bquote() insert symbol formula. example

resp<-quote(sr) bquote(.(resp)~.) # sr ~ .

or can build formula string

resp<-"sr" dep<-"." as.formula(paste(resp,dep,sep="~")) # sr ~ .
