Re: [R] processing matrix equation derived from rows of two matrices

Hi, May be this helps:  tb[1,]%*%(((val-rep(meansb79[1,],5))^2)/6) #    [,1] #[1,] 1.47619 tryvarb-c(1,2,3,4,4,4,4)  var(tryvarb) #[1] 1.47619 tb[2,]%*%(((val-rep(meansb79[2,],5))^2)/6) # [,1] #[1,] 1.904762 sapply(seq_len(nrow(tb)),function(i)

Thanks so much Arun. If you have time, what reference do you use to learn seq_len(nrow…etc and other aspects of your code? Again. Thanks very much. Jan Beckstrand From: arun kirshna [via R] [mailto:ml-node+s789695n4664037...@n4.nabble.com] Sent: Friday, April 12, 2013 2:01 AM To:
