averaging between rows with repeated data
*The situation (or an example at least!)*
example<-data.frame(rep(letters[1:10]))
colnames(example)[1]<-("Letters")
example$numb1<-rnorm(10,1,1)
example$numb2<-rnorm(10,1,1)
example$numb3<-rnorm(10,1,1)
example$id<-c("CG234","CG232","CG441","CG128","CG125","CG182","CG232","CG441","CG232","CG125")
