Hi, I created list of 3 combination numbers (mycombos, around 3 lakh combinations) and counting the occurrence of those combination in another list. This comparision list (mylist) is having around 8000 records.I am using the following code.
myCounts <- sapply(1:nrow(myCombos), FUN=function(i) { sum(sapply(myList, function(j) { sum(!is.na(match(c(myCombos[i,]), j)))})==3)}) The above code takes very long time to execute and is there any other effecting method which will reduce the time. -- Regards, Srivathsan.K [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
