[R] alternative to matching/merge

Subject: Re: [R] alternative to matching/merge? It would be nice if you at least included the code that you are using and a subset of the data. Have you run Rprof to determine which of the functions is consuming the time? On Thu, Jun 12, 2008 at 3:25 PM, Lana Schaffer <schaffer at scripps.edu> Post by Lana Schaffer Greetings, I am doing matching/merge for a table (40919x3) to data which is in. Reduce(function(...) merge(..., all=T), df_list) As recommended here: Simultaneously merge multiple data.frames in a list. If I take the first 1000 items, i.e. Reduce(function(...) merge(..., all=T), df_list[1:1000]) This produces the desired result (merges the individual data frames into a single one) and completes in 37 seconds The right join in R is the opposite of the left outer join. In this case, the merge consists on joining all the rows in the second data frame with the corresponding on the first. X Y RIGHT JOIN. In consequence, you will need to set the argument all.y to TRUE to join the datasets this way Here's an alternative that creates a new vector then assigns the alternating values to it. a <- c(1,2,3) b <- c(11,12,13) x <- vector(class(a), length(c(a, b))) x[c(TRUE, FALSE)] <- a x[c(FALSE, TRUE)] <- b x # [1] 1 11 2 12 3 13 And one more that shows append. c(sapply(seq_along(a), function(i) append(a[i], b[i], i))) # [1] 1 11 2 12 3 1 For large tables in R dplyr's function inner_join () is much faster than merge () For large tables in R. dplyr's. function. inner_join () is much faster than. merge () Using the merge () function in R on big tables can be time consuming. Luckily the join functions in the new package dplyr are much faster
