I've found an instance: > a <- c(0.187,-0.019,0.074,-0.06,0.221,-0.079,0.12,0.079,-0.281,-0.242) > sum(a) [1] -2.428613e-17 The actual sum is 0 but it reports the wrong answer. Maybe it is due to the computer truncation error. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
