This will allow you to read the data frame under a different name but you won't be able to modify it under the different name. We make use of the built in data frame BOD and create the alternate name BOD2: > makeActiveBinding("BOD2", function() BOD, .GlobalEnv) > BOD$Time [1] 1 2 3 4 5 7 > BOD2$Time [1] 1 2 3 4 5 7 > # changing BOD also changes BOD2 > BOD$Time[1] <- 99 > BOD2$Time [1] 99 2 3 4 5 7 -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
