Hi, May be this is what you meant. dat1<- read.csv("data2.csv",header=FALSE,sep="\t") library(plyr) res1<- ddply(dat1,.(V2,V3,V4),summarize,V5=round(mean(V5),2)) head(res1) # V2 V3 V4 V5 #1 1961 1 1 0.52 #2 1961 1 2 0.00 #3 1961 1 3 0.00 #4 1961 1 4 0.00 #5 1961 1 5 0.12 #6 1961

HI, Try this: dat1<- read.csv("data2.csv",header=FALSE,sep="\t") dim(dat1) #[1] 345156 5 res<- aggregate(V5~V2+V3+V4,data=dat1,FUN=mean) dim(res) #[1] 16436 4 head(res) # V2 V3 V4 V5 #1 1961 1 1 0.51761905 #2 1962 1 1 0.0467 #3 1963 1 1 1.14761905 #4 1964 1 1 0.
