Hi, I want to get the unique set from a large numeric k by 1 vector, k is in tens of millions
when I used the matlab function unique, it takes less than 10 secs but when I tried to use the unique in R with similar CPU and memory, it is not done in minutes I am wondering, am I using the function in the right way? dim(cntxtn) [1] 13584763 1 uniqueCntxt = unique(cntxtn); # this is taking really long Please advice. Thanks, Gang ______________________________________________ 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.
