You mean like this? a<-1:10 b<-(a-5)^2 d<-data.frame(a,b) d[order(d$b),] ?? -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces at stat.math.ethz.ch] On Behalf Of mtb954 mtb954 Sent: 24 February 2006 13:55 To: r-help at stat.math.ethz.ch Subject: [R] Sorting a dataframe by one column? Given the following dataframe: A=1:10 B=(a-5)^2 DATAFRAME=data.frame(A,B) How can I sort DATAFRAME increasing (or decreasing, for that matter) by B without making reference to A, or any other column? I've read ?order and ?sort but cannot seem to figure this out. Thank you.
