How to sort a dataframe?
How does one sort a dataframe on multiple columns, say you first sort on variable 1 and then on variable 2, etc.? Is there a simple, one- liner to do this? thanks, Ravi. ----- Original Message ----- From: Spencer Graves <spencer.graves at pdf.com> Date: Monday, April 7, 2003 2:07 pm Subject: Re: [R] How to sort a dataframe?
tester <- data.frame(one=c(3,2,1), two=c(2,3,1)) tester[order(tester$one),]
one two 3 1 1 2 2 3 1 3 2

Dear R-helpers, for the purpose of plotting a dataframe, i am trying to sort a
dataframe by one column, for example
tester <- data.frame(one=c(3,2,1), two=c(2,3,1)) #> tester # one two #1 3 2 #2 2 3 #3 1 1 # I want to sort "tester" by column "one", so that i get a dataframe # that looks like: #one two #1 1 #2 3 #3 2 I know of 'sort' but it can only sort vectors. Thanks for your help, Remko Duursma
