I run this command for converting the numerical variable into factor. However, I get the following error message.
> cols<- c(“GrMM", "RELG", "CASTE1", "SECTOR", "SECTOR4","AGE", "MARITAL" > "JOBSTATUS", "ENG", "EDU", "PARENT_EDU", "MASSMEDIA_F", "MASSMEDIA_M", > "HomeComputer", "HomeInternet") for (i in cols) {data.frame[,i]= > as.factor(data.frame[,i])} Error: unexpected string constant in “cols<- c(“GrMM", "RELG", "CASTE1", "SECTOR", "SECTOR4","AGE", "MARITAL" "JOBSTATUS"" Please help.
