Thanks
Here is another question
I want to have a function that get a string for example
y="AMI" and make commands like the following
agg<-aggregate(numAMI ~MemberID,right.a,sum)
Note that I know that numAMI is part of right.a because another function
with the string AMI already generated it.
Is there a way to do it without paste parse and eval?
I can do it by the following commands for y="AMI"
numy<-paste("num",y,sep="")
texta<-paste("agg<-aggregate(",numy,sep="")
text2<-"~MemberID, right.a, sum)"
text1<-paste(texta,text2,sep="")
eval(parse(text=text1))
If you can have a shorter code for it then it can be productive.
