Hi Assuming the same order in both tables divide only columns you wont and then add column of names. You need to work with data frame, as working with matrices cannot use mixed types columns.
tab1<-data.frame(letters[1:3], 1:3) tab2<-data.frame(letters[1:3], 10) data.frame(tab1[,1],tab1[,-1]/tab2[,-1]) tab1...1. tab1....1..tab2....1. 1 a 0.1 2 b 0.2 3 c 0.3 How to set appropriate column names you can find in help page ?data.frame HTH Petr On 27 Oct 2006 at 18:42, Serguei Kaniovski wrote: Date sent: Fri, 27 Oct 2006 18:42:36 +0200 (CEST) From: Serguei Kaniovski <[EMAIL PROTECTED]> To: r-help@stat.math.ethz.ch Organization: WIFO Subject: [R] How to best divide table by table > Hi all, > > how can I divide two tables of the same dimension so that all names > are preserved, ie do not become NA?
