Thanks a lot all of you Yes, you're right.
However, as i know, "do.call" calls its function once, but "apply(or sapply etc)" not. So, I think do.call is faster than apply. That's why i am trying to use do.call. Am I right?? -- View this message in context: http://r.789695.n4.nabble.com/on-do-call-function-tp3727262p3728700.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
