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.
