Why is the difference between two numbers so different from the "mean relative difference" output from the all.equal() function? Is this an artifact of the way R stores numerics? I could not find this problem as I searched through the submitted bugs. But I am brand new to R so I apologize if there is something obvious I'm missing here. rm(list=ls(all=TRUE)) ## Remove all objects that could hinder w/ consistent output a <- 204 b <- 203.9792 all.equal(a,b) [1] "Mean relative difference: 0.0001019608" a - b [1] 0.0208 ---------- version --------- platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 3.1 year 2006 month 06 day 01 svn rev 38247 language R version.string Version 2.3.1 (2006-06-01) Thanks, Brad ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
