Subject: Help on apply() function
Hi all, can you please clarify me what is the wrong with following codes :
set.seed(30)
z = matrix(rnorm(10), 5, 2)
apply(z, 1, function(x) sum(z[x,1]*1, z[x,2]*3))
However I can not get the desired result. For example, "sum(z[1,1]*1,
z[1,2]*3)" gives -5.822442 which is actually correct. Am I missing something
in apply() function?
Regards,
--
