I am writing a function where the arguments are names of objects or variable names in a data frame. To convert the strings to the objects I am using eval(parse(text=name)):
f.graph.two.vbs<-function(dataname,v1){ val<-paste(dataname,v1,sep="$") val<-eval(parse(text=val)) val } However running this returns an error: >f.graph.two.vbs("data","RECORD") Error in data$RECORD : $ operator is invalid for atomic vectors Repeating the individual commands in the workspace does work though.. Do I need to pass the object data in the arguments for this to work? Thanks, Jorge -- Jorge A.
