I have Windows XP build scripts that look for R in a variety of folders and if multiple ones are found, takes the last one. For example, I currently have the following in \Program Files\R :
rw1060 rw1062 rw1071 rw1071beta rw1081 rw1090 rw1090dev rw1091 rw1091pat rw2000 rw2001beta Note that it currently correctly gets rw2001beta but if I add rw2001 then it will not pick it up since rw2001beta would continue to sort after it. I tried using dates in my scripts to pick out the right one but realized that it was somewhat error prone and decided to move back to ordering by the names. I wonder if a naming convention could be adopted that ensured that the names sort in order. For example, rw2010a - alpha, i.e. development version (previously rw2010dev) rw2010b - beta version (previously rw2001beta) rw2010f - final version (previously rw2010) rw2010p - patched version (previously rw2010pat) Other possibilities might include an ascending numeric or date suffix. I also thought about executing bin\R --version or bin\Rcmd --version in each rw folder but am not sure if this works in all versions and if it does whether the output is always provides a comparable format. ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
