Mean calculated from R1.9.1 different from R2.0.1
...I ran my simulations on the Unix verson of R1.9.1 and the Windows version
of R2.0.1 on XP. I kept getting different values for the mean of the same
column of the same matrix, and am perplexed. I would appreciate if anyone
could help explain the difference?
Here is a sample code:
set.seed(7293)
z1v <- rnorm(1000, mean=68, sd=13)
z1v <- (z1v-mean(z1v))/sd(z1v)
Using R1.9.1 on Unix, I get:
mean(z1v)
[1] -4.88775e-15
Using R2.0.1 on Windows XP, I get:
mean(z1v)
[1] -3.7497e-16
The same problem occurs when I dump the data from one version and
then source it using the other version.
