I am trying to create multiple dataset by group like the following using either
a loop or vectorization:
vocallGp1<-subset(vocallsub, Group==1)
vocallGp2<-subset(vocallsub, Group==2)
vocallGp3<-subset(vocallsub, Group==3)
vocallGp4<-subset(vocallsub, Group==4)
vocallGp5<-subset(vocallsub, Group==5)
When I create the loop I get the following error:
vocallsub<-vocall[c("PatientID","Group")]
>
> for(i in 1:length(vocallsub$Group)){vocallGrp[i]<-subset(vocallsub,
> Group==(i))}
Error in vocallGrp[i] <- subset(vocallsub, Group == (i)) :
object 'vocallGrp' not found
This is my first time attempting to create a loop and am not sure what I am
missing and I need assistance with the proper syntax.
