Hi everyone, I am currently working with a very large data set. It is data collected a few times a day, so there are repeated titles in the data set. I want to assign an id number to each different title and enter this information in a directory that I can access whenever I am working with the data.
An example of a data I am workin with follows: 1 title A 2 title C 3 title B 1 title A 2 title B 3 title C 1 title D 2 title A 3 title C 1 title B 2 title A 3 title C What I have tried thus far is for loops. r<-matrix(x[,1]) t<-matrix(x[,2]) for(i in 1:length(t)) { for(k in 1:length(r)) { z = matrix(c(i,t)) A = "Article A" for(j in 1:length(z)){ if(B=="Article A") else{enter article in z} } } This is of course giving me a lot of errors. I just have no idea where to go with this. Does anyone have any ideas on where I can go from here to create my directory? I appreciate all your help. Thank you in advance. -- View this message in context: http://www.nabble.com/Creating-a-directory-for-my-data-tp22448335p22448335.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.
