for example (not sure if representative example though): n <- 1e6 d1 <- data.frame(x=sample(n,n), y1=rnorm(n)) d2 <- data.frame(x=sample(n,n), y2=rnorm(n)) this i've got far: d <- merge(d1,d2) # 7.6 sec library(plyr) d <- join(d1,d2) # 2.9 sec library(data.table) dt1 <- data.table(d1, key="x") dt2 <- data.table(d2, key="x") d <- data.frame( dt1[dt2,list(x,y1,y2=dt2$y2)] ) # 4.9 sec library(sqldf) sqldf() sqldf("create index ix1 on d1(x)") sqldf("create index ix2 on d2(x)") d <- sqldf("select * d1 inner join d2 on d1.x=d2.x") sqldf() # 17.4 sec the match approach works when there unique key in second data frame each key value in first. if there duplicates in second data frame match , merge approaches not same. match is, of course, faster since not doing much. in particular never looks duplicate keys.
