Otherwise you can try following: x <- c(1,5,100,300,250,200,550,900,1000) which(x==quantile(x,0.25,type=3))
This will always return number within your vector. See further information with ?'quantile' Thanks and regards, -- View this message in context: http://r.789695.n4.nabble.com/Percentile-rank-for-each-element-in-list-tp2529523p2530029.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.
