[R] counting similar strings in data.frame
Dear Members, is there a better solution to count the amounts of occurrence in a row with string data than with loops to get the count data.frame? test =data.frame(first=c(seven,two,five,four), second=c(three,one,three,one), third=c(four,two,three,four), fourth=c(four,one,one,four)) count =data.frame(double1=c(four,two,three,NA), double2=c(NA,one,NA,NA), triple=c(NA,NA,NA,one)) double1: first double occurrence in row (NA if triple available) double2: second double occurrence in row (NA if triple available or if there is only one double) triple: triple occurrence in row (NA if a double available) Kind regards Knut __ 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.
Re: [R] counting similar strings in data.frame
Sorry last count was wrong ... test =data.frame(first=c(seven,two,five,four), second=c(three,one,three,one), third=c(four,two,three,four), fourth=c(four,one,one,four)) count =data.frame(dobule1=c(four,two,three,NA), double2=c(NA,one,NA,NA), triple=c(NA,NA,NA,four)) __ 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.

Re: [R] counting similar strings in data.frame
OK. I do not have canned solution for you, but temp - apply(test,1, table) gives you number of occurences in each row. From this it shall be possible to extract name info and number info lapply(temp, function(x) x[x1]) [[1]] four 2 [[2]] one two 2 2 [[3]] three 2 [[4]] four 3 Here you have numbers and strings and you need to combine them. However I am not sure how. If you want to use them for some further computation, maybe list structure is as good as data.frame with namy NAs.
