Selecting A List of Columns
...deVars<-row.names(NodeImportance)
NodeVars<-data.frame(NodeVars,stringsAsFactors = FALSE)
colnames(NodeVars)<-"Vars"
ImportantVars<-rbind(MSEVars,NodeVars)
ImportantVars<-unique(ImportantVars)
nrow(ImportantVars)
ImportantVars<-as.character(ImportantVars)
ImportantVars
CarsVarsKept<-subset(mtcars,select=ImportantVars)
Error in `[.data.frame`(x, r, vars, drop = drop) :
undefined columns selected
Any help on how to select these columns from the data frame would be most
appreciated.
