Dear all, it looks like fix() changes the class of mts objects, here is a reproducible example (tested both on WinXP and Linux):
> x <- ts(cbind(1:5,1:5)) > x Time Series: Start = 1 End = 5 Frequency = 1 Series 1 Series 2 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 > class(x) [1] "mts" "ts" > edit(x) Series 1 Series 2 [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5 > class(x) [1] "mts" "ts" > fix(x) > class(x) [1] "matrix" > x Series 1 Series 2 [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5 > R.version _ platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 5.0 year 2007 month 04 day 23 svn rev 41293 language R version.string R version 2.5.0 (2007-04-23) > R.version platform x86_64-unknown-linux-gnu arch x86_64 os linux-gnu system x86_64, linux-gnu status major 2 minor 5.0 year 2007 month 04 day 23 svn rev 41293 language R version.string R version 2.5.0 (2007-04-23) ______________________________________________________ Simone Giannerini Dipartimento di Scienze Statistiche "Paolo Fortunati" Universita' di Bologna Via delle belle arti 41 - 40126 Bologna, ITALY Tel: +39 051 2098262 Fax: +39 051 232153 ______________________________________________________ [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
