\'order\' in R seems like \'sort\' in Stata. Here\'s a dataset for example (only variable names listed):
v1 v2 v3 v4 v5 v6 v7 v8 v9 v10 v11 v12 v13 v14 v15 v16 v17 v
This should give you the same file:
#snip
gtinfo <- rbind(tweetinfo, noretweetinfo)
gtinfo$deleted=""
retweetinfo <- transform(retweetinfo, reTweetId="", reUserId="")
gtinfo <- rbind(gtinfo, retweetinfo)
gtinfo <-gtinfo[,c(1:16,18,17)]
#snip
It is possible to implement a function like Strata's order function in R, but I don't think there is much demand for that.
